This app has been offering me a free upgrade for a drink for over a year now and eveytime I try to accept it, it goes into cart and asks me to add the item despite picking it in the offer. It then never allows me to add it with an increase in the cost. I end up with an increased cost in my cart. This seems like a scam to get me to pay more. Please advise and correct I have tried over and over to figure out what to do, I have sincerely tried with patience. This is very frustrating.
