Email support@mastaprep.com. Tell us what happened and include your account email or payment reference where relevant. For a question error, use the question’s report control or include its reference. Never send your password, full card number or identity documents by ordinary email.
Billing: payments, renewals, cancellations, refunds or missing access. Most of it you can do yourself in Settings → Plan and billing; a parent who paid can use Manage my payment.
Learning support: an explanation that seems wrong, a broken feature or difficulty using the site. The help centre covers the common questions.
Privacy and safety: account information, deletion, guardian requests or concerning behaviour. We may verify identity and authority before sharing personal information.

Grievance officer: Aakash Sureka, Proprietor. Email support@mastaprep.com, with “Grievance” in the subject if convenient. You do not have to use that exact subject for us to handle your complaint.
We acknowledge consumer grievances within 48 hours and seek to resolve them within one month, subject to applicable legal deadlines. We will provide a reference and keep you informed where further investigation is needed. This process does not prevent you from using available consumer or privacy complaint channels.
After you answer a question and read its explanation, there is a “Something wrong with this question?” link under it. Tell us what looked wrong and it reaches us attached to the exact question you saw. It does not change your result and it does not hide the question. If we agree, the fix is a new reviewed version rather than a silent edit — see how our content is made.
