Returned equipment still being billed

I am not sure of a solution as I tried everything to show them that I did in fact send my Gateway back after discontinuing my TMobile Home Internet. Nothing worked and I just saw that they sent it to collections so it's now affecting my credit. I have had no luck trying to talk to anyone at TMobile, I have been treated as though I was trying to scam them or something. Really? Over something that I can not use unless it's with their service, that rarely worked anyway?! Come on, get real. What purpose would I have for keeping that thing? My first gateway went bad so they sent me a new one and I sent the old one back and had the same issue. Luckily, I was finally able to speak with someone who actually listened to me and wanted to help me. It still took a month or so get it taken care of, during which my service was disconnected twice because of the additional $350 on my bill that I did not owe. Both times I had to pay the $30 re-connection fee.

I wish you the best of luck with this. Hopefully you can get it figured out before it ends up in collections and affecting your credit. If you do figure it out, please let us know how you were able to get it done!
