Three channels for CS homework help support: email, WhatsApp, and live chat. Median email response is 28 minutes during operating hours, WhatsApp 9 minutes, live chat 14 minutes. New assignments route to the submission form for tutor matching; policy questions, refund requests, DMCA notices, and accessibility reports each have a dedicated intake path.
Channels
3 ways to reach support
Fastest channel for a tight deadline. The WhatsApp inbox routes to the same Slack thread the matching team uses to assign tutors. Text and voice notes both supported.
Live chat
Bottom-right corner of every page
Sits between email and WhatsApp on speed. Good for a pre-purchase scope question or a quick clarification on an in-flight order. Agents can open a refund ticket but cannot approve refunds directly.
Response time SLA
Most inquiries clear in under 30 minutes during operating hours. The published medians across the last 6 months of support tickets sit at 9 minutes for WhatsApp, 14 minutes for live chat, and 28 minutes for email.
Operating hours run 8am to 11pm Eastern Time, 7 days a week, on email and live chat. WhatsApp carries continuous coverage across the 4 timezone bands (EST, PST, GMT, IST) the tutor pool covers, so an overnight EST question catches an IST morning-shift agent.
The overnight email and chat gap (11pm to 8am Eastern) tracks a 2-hour 14-minute response median; for anything time-critical inside that window, WhatsApp is the right channel.
Routes by intent
5 intent-specific paths
New assignment submission
Skip the inbox round-trip. The submission form takes the brief, the rubric, the starter code, and a deadline in one upload. A verified tutor confirms scope inside 15 minutes. Median full reply time is faster than email because matching, pricing, and tutor introduction all happen in a single form-driven flow.
Open the submission formRefund request
Email [email protected] with the subject line "Refund request, order ID" and the order ID in the body. The published refund policy covers eligibility, the 15-day claim window, and the partial-refund grid. Live chat agents open a ticket but cannot approve a refund directly.
Read the refund policyDMCA notice
DMCA notices route to the designated agent under 17 U.S.C. section 512(c)(3). The notice carries the rights holder signature, identification of the protected work, and the URL of the alleged infringement. Section 4 of the DMCA page lists email and postal intake addresses; section 5 covers the counter-notice procedure.
DMCA takedown procedureAccessibility barrier
Email with the subject line "Accessibility" and include the page URL, the assistive technology in use, and a description of what blocked the task. The team responds within 5 business days. The published accessibility statement covers the WCAG 2.1 AA target, the tested screen-reader stack, and the open remediation backlog.
Accessibility statementGeneral CS help question
Pre-purchase scope questions, language coverage questions, course conventions, and tutor availability questions go to live chat or WhatsApp. The team can match a tutor against a course code (CS61B, CS50, CMU 15-213) before any payment so the student sees the named expert before committing.
How CSHH worksPress and partnership
Press queries, partnership inquiries, and integration requests route to the [email protected] address on the parent organization. CSHH is operated by WitNip Inc, a Delaware-incorporated company. Response time on parent-org inquiries runs 1 to 2 business days.
About CSHH and WitNipWhat is not on the contact surface
Voice phone support is not offered. The technical nature of CS support (compiler version, stack trace, rubric URL, starter code, autograder output) tracks better in writing than over voice, with fewer round-trip clarifications. WhatsApp on +1 302 520 2767 is the closest substitute and accepts both text and voice notes.
Mailing address is not published on the contact page; the DMCA postal intake on the DMCA page covers the only case where postal mail is the right channel.
Social-media DMs to any account claiming to be CSHH are not monitored; treat any such message as a phishing attempt and route the query through email or WhatsApp instead.
FAQ
Contact FAQ
What is the actual response time on email?
Median 28 minutes during operating hours (8am to 11pm Eastern Time, 7 days a week), 2 hours 14 minutes on the overnight queue (11pm to 8am Eastern). The team replies from [email protected]; check the spam folder if the reply has not landed inside 1 hour.
Which channel is fastest for a tight deadline?
WhatsApp on +1 302 520 2767 carries the fastest queue (median 9 minutes during operating hours) because the inbox sits on the same Slack thread the matching team uses to assign tutors. Live chat sits second at 14 minutes; email sits third at 28 minutes.
Do I need to use a specific channel for refund requests?
Refund requests route through email with the subject line "Refund request, order ID" and the order ID in the body. The published refund policy section 6 covers eligibility, the 15-day claim window, and the partial-refund grid. Live chat agents can open a ticket but cannot approve a refund directly.
How do I file a DMCA notice?
DMCA notices route to the designated agent listed on the published DMCA page. The notice requires the rights holder signature, identification of the protected work, and the URL of the alleged infringement under 17 U.S.C. section 512(c)(3). Email and postal channels are listed in section 4 of the DMCA page.
What if I have an accessibility barrier on the site?
Email [email protected] with the subject line "Accessibility" and include the page URL, the assistive technology in use, and a description of what blocked the task. The team responds within 5 business days. Accessibility fixes take priority over cosmetic work in the queue.
Can I call a phone number for support?
Voice support is not offered. WhatsApp on +1 302 520 2767 is the closest equivalent and handles both text and voice notes. The reason: the technical nature of CS support (compiler version, stack trace, rubric URL, starter code) tracks better in writing than over voice, with fewer round-trip clarifications.
When is the team online?
Email and live chat carry 16-hour daily coverage from 8am to 11pm Eastern, 7 days a week. WhatsApp runs continuous coverage across the 4 timezone bands (EST, PST, GMT, IST) the tutor pool covers. The overnight gap on email and chat (11pm to 8am Eastern) tracks a 2-hour 14-minute response median.
