We’re really sorry to hear this — we understand how frustrating it can be, especially when you’re expecting cashback and see failed transactions.

Cashback tracking can sometimes be affected by factors like activation status, browser settings, or merchant tracking conditions, which may cause some transactions (including Temu or Amazon) to not track successfully.

We’d really like to look into your specific orders and help figure out what happened. Please reach out to us at tphelp@coupert.com
with your order details or screenshots, and our team will investigate this for you as soon as possible.

We truly appreciate you bringing this to our attention — we’re here to help.
