T-Mobile non return fee on gareway scam

They said for for me to keep calling and when the device is there they will make a decision. I was like $467 extra on my bill. I even told them why didn't anyone just call me and ask me to return or I will have to pay a fee. Think about it what do I need a internet box for if I canceled it and said I don't want it anymore. Besides it was way too much money for the internet and the deluxe speed. Not worth it. They wouldn't even take it at the store they said I have to ups it so I did. It's not fair if I returned it and still have to pay for it when I only used it for like 2 months.
