UberEats is a fruad!!!

UberEats is a *****!!! A friend sent me a link to download the uberEats App where I would get a R50 promotion off of my first meal. First I could not verify my app, than when i tried to check out it said the promotion was not available for the account and than it said i had already used the promotion, which I didn't because i could not even check out without receiving some sort of error message. I will never use Uber or UberEats
