You get de*****ed and the banks service is the worst

There was money taken out from my account I called them and adviced them the lady I spoke to adviced me that they would refund the money in 30 days and that she has opened a ***** case 30 have passed no one has called me to give me feedback i used they whatsapp chat that was useless im left with debt I cant pay becuase capitec did not take my ***** case seriously I didnt even get 1 phone call from them to advise how far .my case is and no refund....the service is appalling I really want to cancel my account and advice my friends and family to do the same
