Terrible service!

Just for context, Verizon has coverage and speed problems as well.  I was with them for 15 years or more and they used to be pretty good, until about 6 months ago.  After what I've been able to discern, they did some software changes on the towers, my phone almost quit making calls, (my mom's phone that piggy backed on Verizon's towers quit working all together, and her company had to send a new phone to get her service going again).  I could hear the other party but they couldn't hear me.  Verizon was no help, they said all was good and i could buy a new phone and a more expensive plan.  Some fix, all this after a $6.00 sur charge in the summer, mmm just because.  I told them if they didn't make an effort to help a good paying customer I would leave to T-mobile.  They were unconcerned, so I'm here now.  So far service in my semi- rural area has been 100% and great call quality and I've logged download speeds as high as 40 Mbps.  I expect in a more city environment my speeds will be even better.  I went from a limited Verizon plan to an unlimited T mobile plan for less money.  Time will tell, but as of right now I'm glad I gave Verizon the boot.  Just another perspective.
