Unauthorized purchase transaction

Unauthorized purchase from rain, 3 transactions capitec is taking me from pillar to post and 1 consultant even when to an extent to tell me that I'm the 1 who gave people my card number, since I once paid for someone, and they need proof of cancelation before they can assist me. I kept on trying to explain that even if that is the case,rain is a month to month its not a contract, they do not give or send cancelation letters since it is not a contract and also I do not have any agreement with rain network whatsoever. The lady insisted that is how they work. I then asked about any communication from them cause it's been more than 2 days and I don't know what is happening I just need my money to be transferred back to me. I was told Capitec bank does not call any clients it is the client's responsibility to follow up, which I found very odd, what type of a company does that, poor customer service.

Capitec clearly will not assist me iv been a client for more than 6 years but the service and treatment it feels like they are doing me a favor, I will be in debt since I am now short with R2 914. 00.
