T-Mobile Ripped Off & Lied too! Fitchburg, WI Nationwide

I purchased one new phone and 2 sim cards on 9/20/2017 due to the fact that Luke, T-Mobile Store Manager, said that the T-Mobile service would work just fine where I lived. He stated that I was right between two of their cell towers. However, after arriving home that night, the two phones would not make calls nor receive data. When I did get data through, it was very slow. I called tech support that night after midnight. I called again the following afternoon to level 2 tech support. She informed me that I lived in a bad area and after running several Speed tests. They were all like 1.3Mbps down and .064Mpbs up. Tech support said that is the best I can get where I live. It was 2G at best. She said that because of this situation, I should get all my money back without any restocking fees. T-Mobile refused, after only 2 days to reimburse me and the way I look at it, still owes me $105.51. Several times it would just say Communications Error - it wouldn't even connect to the cell towers at all. I may be looking at this all wrong but I feel I was lied too and deceived and ripped off.
