Poor service

Really dissatisfied with standard bank. I forgot my wallet at home and decided to use instant money to draw money for lunch. The ATM in Cavendish wouldn't allow me to withdraw my money. I then tried another voucher and the same thing happened . I called standard bank and they advised me how to cancel the voucher. Now I am being charged for something I couldn't use, and when I called your call centre I received the worst service possible. After explaining what my problem was the guy put me on hold for a long period, when he got back he asked me 'how could I help you?' Unacceptable service from standard bank. He then said all managers are in a meeting and couldn't assist me. If you fail to refund me due to your error I will be broadcasting your service on a media website very soon
