Capitec unauthorized debit

I'm utterly disappointed in this bank I'm even decided to another bank...so last month I had an unauthorized debit order with a reference Microsoft I googled the company which I'm still shook they could get my banking details without my consent I immediately went to the bank the consultant told me about an R80 charge for the investigations which I still don't understand it's purpose he immediately changed my card which I had to pay for even though the bank and it's weak security system is at fault okay I received a call from Capitec I was happy with how quick my complaint was attended too great!now new month my authorized debits can't go through because they've placed my limit to a R0 I immediately increase so my debits can take their money well the Microsoft reference is back and has debited again like I'm yet to understand why this keeps happening Please advice I've been with this bank for a long time now and Abigail who was in charge of my matter said it won't happen I'd appreciate it if she called me again to explain why this keeps happening

Unhappy customer
