Oh my goodness! I am so sorry that your experience has started off on the wrong foot! It is true that most BOGO promotions do not stack with the Get Out Of the Red promotion as both promotions are centered around a device. With get out of the red, we are reimbursing you device payment plans on the phones you are bringing over. With a BOGO, some require a trade in of a fully paid off phone. Since we are the ones paying off your phone, stacking on a promotion that allows you to get a free phone by trading in a paid off phone would almost be a double dip which is why we do not allow them to stack. Again, I sincerely apologize that this was not communicated to you when you were at the store but I would be more than happy to pass this feedback along so that the proper education can be relayed. I will send you a private message so I can gather some more info about the store.
Your situation is terrible, hopefully T-Mobile will rectify this situation.
I think my experience was even worst. Its a Kafka novel. This company wont last
