How to file a complaint

  1. Email grievance@quantumsi.in with the subject “Grievance”, call the Grievance Officer, or write to him at our registered office. If you have a QSI account and you email us, write from the email address you use to log in.
  2. Tell us what happened and what you would like us to do (see the list below).
  3. We confirm that we have received your complaint and give you a complaint reference number.
  4. We look into it and tell you the outcome by email, within the time limits below.

How long it takes

As the Consumer Protection (E-Commerce) Rules, 2020 require, we acknowledge a consumer complaint within 48 hours and resolve it within one month of receiving it. This covers complaints about the service, your account, a payment or a refund.

Complaints about how we handle your personal data are answered as section 8 of our Privacy Policy explains.

What to include

  • Your name, and the email address you use with QSI (if you have an account)
  • What happened, with the date and time (IST), and the feature or page involved
  • For a payment or refund issue: the order or payment ID, the amount, the date and how you paid (for example UPI or card)
  • Screenshots, if they help explain the problem
  • What you would like us to do to put it right

Please don’t include passwords, login codes, OTPs, your UPI PIN, full card numbers, CVV, bank account numbers or ID numbers such as Aadhaar. We never need them to look into a complaint.

Other ways to get help

We hope to put things right with you directly. You can also contact these government services, for example if you are not satisfied with our response:

Consumer commissions

File a consumer complaint online through e-Daakhil at edaakhil.nic.in.

These are Government of India services, not run by QSI. Our Terms are governed by the laws of India. This does not take away any right you have to approach a consumer commission under consumer protection law.

Privacy and your data

To access, correct or erase your personal data, withdraw your consent, or nominate someone to act for you, email privacy@quantumsi.in from the address you use with QSI. Complaints about how we handle your personal data can go to the same address or to our Grievance Officer.

You can also delete your account yourself at any time in QSI: Settings → Account → Manage → Delete account.

Our server doesn’t store your chats, so we can’t find or delete them for you. Your chat history is saved only in your browser, where you can delete it with Settings → “Clear all”.
