Merrick Bank Credit Card review: Two fraudulent charges totaling $154 each posted to my credit card account

In march of this year I joined vintage sansui hifi components group on facebook seeking a part for sansui 1000a vintage stereo receiver a scam artist in the group who appears to be located overseas and who appeared to have stole a U.S.A. Facebook user id located in Ohio approached me by texting me in facebook massenger that he had got a complete working sansui 1000a receiver if I paid him $300 online using a credit card that he will ship it to me immediately after receiving credit card info he wanted photo of the front and back of my credit card, I forwarded my merrick bank credit card pic of front and back side with security code on back once he got this info he tricked me into calling merrick bank and telling them to approve his two payment totaling $154 each once this was done he got the money and disappeared I never received the tracking number from fedex ground he promised he would ship and I never received the receiver from him. This bank after month long investigation decided in my favor and recently I was shocked to learn the very turned around and reversed the out come and reinstated the the fraudulent payment charged to my credit card by this overseas scam artist, this bank provided no evidence why they thought these charges were valid, they are facilitating crime commited by this scam artist online while all the time assuring the credit card holder we will here to protect you against fraudulent charges posted to your account, the letter by their security dept gave a number to contact them to discuss the matter, but even after more than 1 hr wait put on hold no one comes on phone so the customer can file a dispute, very disappointed i. This bank I am thinking of cancelling my credit card from them as I have lost faith in them for protecting me against fraud commited against me
