Terrible service from Uber Eats.

I ordered food from KFC Sunninghill , driver got to my work and came inside to ask for me - the lady in front said to leave food with her and she will get hold of me to come collect my food , then the driver just walks away with my food and cancels the order. This is disgusting service and uber contact details dont work and cant get hold of them anywhere. They take forever to reply. I want my refund from uber.
