Uber Eats terrible service

I placed an order of food from Mug n Bean on Saturday afternoon, with delivery for Sunday morning. The funds for that order were taken from my account at 14:40 PM amount of R158.90. That same evening at 20:42 PM the amount of R158.90 was reversed into my account without my having cancelled the order. So at 02:29 on Sunday morning i placed another order at Mug n Bean for R171. When i went to pick up my order at Mug n Bean i found both orders prepared; i told them i cannot be paying for 2x orders when i had done nothing for the funds for the 1st order funds to be reversed into my account. I subsequently left Mug n Bean with one order and refused to accept the the 1st order. When i got home i saw that the funds from the 1st order were also taken from my account in two installments ; R144.45 at 09:03 and R14.45 at 10:03. I tried calling support but the option for Uber Eats is not being attended to. I was given an email address to submit my issue but apparently that is unattended to as well.
