Uber eats has a ****ed up customer service

I ordered a meal worth R220.47 and I had explained before that I received a voucher worth R250 from DStv rewards and was informed to pay for the meal using my personal card and my voucher will be app**** to the trip.

I did so and was informed the following day which was the 13th November 2023 that the voucher has been app**** and indeed it was and that I will get my refund after 7 working days.

To this day I still haven't received my moment and when I visit the help section for assistance they close the chat on me without assistance or spend days without getting back to them , when they do they would say "please elaborate in a brief manner" whereas I already did. With the first voucher I used I didn't have issues but this one I don't know why are they not refunding me,7 days long passed. This is poor service honestly speaking!!!! I just want my money so that I can stop using their service.
