Bad service

We have a society of 6 ladies and we paying each other monthly now it was Zinhle Makaye turn to pay us this month and few days after she had paid us, she went to block our accounts at Capitec saying we are dealing with *****. Capitec did not contact any of us about this, we only see when we want to do transactions that our accounts are blocked. This clearly shows that Capitec Bank is *********** because anyone can just call and say anything to them and they block account without any evident proof but a hearsay what's worse they don't even contact you to ask, they just block.
