Yes, report this at once. It happen to me last week as well. I report it immediately and get the CS involved. my usdt remain freeze for over 24 hrs.

Peace be upon you
Yesterday, I was selling USDT to a guy in a P2P trade. He marked the payment as done without actually making the payment. When I checked, the payment had not come through. He kept insisting to quickly release the USDT. I double-checked, and there was no payment. The purpose of sharing this is to advise you to never release USDT in a hurry unless you are sure that the payment has been credited to your account. There are many scammers on P2P, so please work with caution.
Thank you.
