Passing my information to third parties without my

I just received a call from this number *** and this person informs me that she is calling me on behalf of some company I do not know because I am a client of Capitec. This is how I was de*****ed of my funds with the previous Capitec account which I had to close because Capitec failed to stop these unauthorized debits on my account. It seems clear to me that this bank does not curb *****, but in fact encourages it by giving away client information to external parties without the client consenting to such. If I should see an attempt to debit my account, I will take it as a direct aggression against me by Capitec and I will escalate this. Whoever is responsible for this better sort it out ASAP or else heads will roll!
