Uber *********** support staff

I have been trying to get Uber to remove an outstanding balance on my account since the 22 December 2023. What happened was. I accidentally subscribed to their Uber one membership. They Deducted R500 from my bank account. I cancelled the membership like 30 min after opening it. Uber said that it was fine. Paypal reimbursed my money, but Uber has placed an outstanding amount on my account, therefore I am unable to use it. I have talked to a lot of different support staff, I have sent them numerous bank statement, and the transaction statement from Paypal. They don't have the skills to sort this out for me, or they don't care.
