T-Mobile must be related to Verizon. Paid for service promising excellent service better than Verizon, and got poor to no service didn't work, never to the service promised. Customer service tried sell me upgrades but said no. After some attention, no luck in the quality of service so I left. Got harassed because they want money for poor to no service. Months after leaving, T-Mobile wants free money for poor to no service, just like Verizon. Poor to No Service, No Money.
