Cathay Bank Bank Account Or Service Complaint

Cathay Bank Bank account or service department,

Checking account Account opening, closing, or management New York

I have had a basic, no monthly fee bank account with - Bank until around middle of 2015 when - Bank was acquired by Cathay Bank and all the - Bank accounts were transferred under Cathay Bank. My account was also transferred under Cathay Bank but instead of the same basic no monthly fee account I used to have it was the type with $ 15 monthly fee. When I opened my bank statement from Cathay Bank and saw the $ 15 monthly fee, I decided to go the bank branch and inquire about the fee. The manager said the bank has sent all customers about the account type change and refused to refund the $15.00. I believe from a matter of principle what Cathay Bank has done is not right.
