Capitec partnering with Uber on *****

For two months Mar and Apr I have been having Uber and Uber eats transaction on my credit card - same amounts until they exhausted my balance. I went to Capitec twice and they told me it’s not their problem, I gave Uber my account details and accepted that they can share my details with whomever they partner with, I must just put my online shopping limit on R0 and take it up with Uber not them, they will not assist and Uber is saying nothing. Now my problem with Capitec is that with online shopping they ask you to approve any payment before it’s deduct but not with Uber…yet, this is now my problem. Can someone advise on steps I can take to resolve my issue and get my thousands back
