Uber Eats billed me twice for 1 order.

If I could, I would give the No star. On Sunday the 29th January I ordered KFC via Uber Eats, the charge was R62.50, I gave the delivery man R100 and he said he didn't have change as all his orders that whole morning were card payments. I went into my workplace and asked for change, came back and paid him. On Tuesday the 31st I get into my Uber Eats app and get an error that says I should pay my last order of R62.50 before I can order again. I sent an email complaining about this and was told "unfortunately it's over 48 hours and I cannot be assisted" wow. Si I was billed twice for 1 order.
