Several Orders paid for but never received

I am a regular customer for this company however, the treatment I receive is not one I expect. On more than one occasion I have been paying for food I never receive. I always get a receipt at the end of each order however, I never get my food.

what annoys me the most is that uber eats is not reachable on phone call there is no contact number to reach them on for such complaints. The online live chat does not help either because it is always offline and also unreachable.

I do not know what to do anymore. Please help as soon as possible.
