*****ulent debit order

The bank approved an unauthorized debit order from my account. I called the bank after disputing the transaction in the app, they provided a number for the company(Netcash serv) that facilitated the transaction. I then called the company that facilitated the debit order and they also gave me a number for the bogus company the claim to have facilitated the debit order for. When I called the number multiple time, it was not answered. Apparently the name of the company is Sa Unathi

I have never heard of this SA UNATHI and I cannot get any answers as to where they got my banking details. The bank cannot tell me why the debit order went off without authorization. I have been charged for the dispute and all the debit order fees though. Now I not even certain if this is the first time ti's has happened. I have lost trust in Capitec Bank and considering to change banks.
