Revvi Bank review: Revvi credit card account number [protected]

I Got a credit card from REVVI BANK. ITS supposed to help build your credit. it has completely ruined my credit. i received the card July 23,2022. i used it twice and then on august 2,2022 there were fraudulent charges on it. I contacted Revvi and reported it right away that was August 2,2022. Ive been waiting for it to be resolved since then and have it removed from my card but it has not been removed. Now Revvi is saying I have to pay it back. When i call there is no fraud department and the customer service is horrible Please help me.
