Instant money

I did instant money transfer on the 15 July 2015. The person I was transferring to could not withdraw because the ATM gave a technical error and other ATM say the voucher has already been used. I went to the bank, they called the call centre and got a reference number. The person that took the call was Gugu. She said this will be resolved within 24 to 48 hours. This hasn't been resolved yet. I called the call centre. The line got cut off the first time after 5 minutes. The second time I was holding for 8 minutes. Please just give me my money back.
