UberEats false advertising

I ordered from Pizza Hut today via Uber Eats, the buy one get one free promotion. I got only one meal, Uber eats is giving me stupid excuses why my order was not complete, "that I placed the order wrong" and then again it changes to "the restaurant was not part of the promotion". This is false advertising, robbing people. I see a lot of people are victims of this today... This is unacceptable!!!
