T-Mobile Tmobile Worst Service Ever Chandler, AZ Nationwide

 I changed from AT&T to Tmobile only two months prior to this report, and it has been just the worst service I've ever had. The customer service at the Chandler, AZ location was actually very good, but the cell service itself is just awful. I work in a very populated metropolitan area so service should be very good. There are only 4 places in the entire city that my service works. I've even driven up next to the cell tower and it still didn't work. I thought it could've been the iPhone 6+ I was using and the manager at the chandler location met me swap it out for a Samsung S6, but the same issues were happening. I drop almost every single call, my texts ALWAYS have to be sent multiple times, and I often don't ever receive texts sent to me. I really just want AT&T back but can't afford the fees. Tmobile promised to pay for the early termination fees when I switched carriers, and I even sent them a copy of the bill reflecting how much that would be. I received only about half of what my actual early termination bill was and had to pay the rest. I am always on my phone and tablet so having shaky service like this is really depressing. I just cannot believe how awful it is. After speaking with anyone and everyone I come across about their cell service, I've concluded that everyone who has Tmobile in my area has terrible connection.
