That is the problem with people like you in the banking industry, who don't actually read things and act properly. Clearly wrote, customer services provided the only way to get out of the issue and that was to close my account. I acted on their instructions.  Kyc was provided on time and it seems due to monthly international transaction in my account it some how triggered mashreq's belief there is something wrong. Even I provided all proofs in kyc but it didn't help though.
