African Bank is the worst bank!

Once again I'm having issues with African Bank MyWorld Rewards. I called the call centre and was told I didn't swipe 10 times for the month and I literally had to tell them to check my bank statement as I swipe more that 10 times every month! I was then put through to the rewards centre, the guy who assisted me was so friendly and helpful only to con me by sending me a invalid rewards voucher. This is not the first time this is happening to me! African bank has embarrassed me a few times already with their non working vouchers! Im definitely thinking of moving to Capitec, been hearing their praises while I've been complaining about my bank! When I called them back to let them know the voucher they sent me was invalid they apparently couldn't put me through to their rewards centre and told me I'll receive a call from them but its been a week and still haven't received a call! To think I used to tell people to move to African bank because of their costs but their service sucks! So I'd rather pay a small fee and get proper customer care.
