Instant money not put back in my account.

I sent myself a instant money voucher on saterday and it did not work so i try to reverse it the money har not been placed back in my account. Every time you phone you wait 15 to 20 min plus EVERYTIME since ive been with this bank. When i get to talk to someone im just told its a glitch case will be escalated. I moved to standard bank 3 months back. Wost move ever!!!!
