Capitec response to my complaint

I went to Capitec today complaining about the Uber eats **** that took my money. I asked them how come I didn't get an authorisation message for the order, they don't even have my pin code how come.

The response I got was, there is nothing they can do I was suppose to not leave my bank details on Uber eats and online purchases was suppose to be on R0 all the times.

They even said Uber eats does that and I told them I didn't know about that, and if they are aware about this Uber eats **** what they are doing about that. I'm not happy with that response I want my money back.
