Ubereats just takes my money with no verification.

I joined on the 19th of May 2020. My experience was bad from the start. I struggled for about 4 hours to get my account verified to place an order only for it to tell me that my account is locked until I verify it in the app. This was impossible as the app won't verify my account. They won't even verify my email address. Then a R50 for free delivery was taken off my account. Is this how they make their money by just taking off money. They took off the R50 without verification but I can't use their service because my account can't be verified. So how can they just take money off my account but I cannot use the service because they won't verify my account. I can't find a way to contact them for them to reverse the money as I can't use the service so I lost R50 for nothing. I can't find a way to email them and the call center is not available. So how do I get my money back and delete this service?
