Complain of being overcharged

<p>This bank is charging a R100 of bounced debit oder which I don't understand why, so I tried calling their customer care line I first spoke to Mpho from their complain department but she didn't help me at all she just put me on hold for about 3 minutes I ended up hanging up cause I didn't have enough airtime. Then charity called me and asked her why they're charging me and she said she can't exactly tell me why but how it works. So clearly they just over charging us with any valid reason and disgusting. </p>
