Bunch of ****ing ****mers

Two transactions were deducted from my account from a person overseas. Took it up with UberEATS, they say there are a link between me and the other account holder. I am in South Africa and he is in ****ing Tunisia. i don't even know where that is or any person there. They refuse to refund my account! I will not use this Uber anymore, please do not link your bank card for payments on their app! bunch of ****ing ****mers!
