Doesn't honor their Promo codes

used a promo code .. they accepted it but after bill was nothing taken off. They said " sorry you have to put code in first" Surprisingly I had .. when it didn't take off money I thought wrong browser so I swapped and redid browser .. When I tried dif codes it said" you already have a code app****" After I informed them they said the code wasn't available in my area.. Code for we are a ******* company that doesn't honor codes if we can trick you into using one. If wasn't allowed why the #$%@$% did you accept it ??? Uber and Uber eats are now deleted from anything I will ever use .. and I am passing the word around to everyone I know (and everyone they know) thank you for showing your true colors Before other people made the same mistake!!
