I have bad experience with Mashreq bank.
1) Most of the staffs do not respect the customers and rude specially Arab staffs;
2) When I requested bank statement for family visa, It took two weeks, and I had to pay QR 10 for each page;
3) I got sms from the bank stating that MEMBERSHIP FEE of QAR30.00 has been debited in my account, it happened three months continuously. When I inquired, they said it was technical fault. This amount was adjusted after several calls & e-mails;
4) After few years, I went to the bank and requested to close my account. After the paper work, I asked to give receipt/letter for confirmation that the account was closed. She said in order to get the receipt/letter I need to pay cash. Then I told to her no need receipt close my account. Until now my account was not closed. May be I need pay cash to close my account.
