Have been Sprint customer since '98. 6 lines, great standing, etc. Now that Sprint is part of T-Mobile, trying to decide if it's time to move on since first impressions with T-Mobile customer service and support have been underwhelming. As I am being squeezed by T-Mobile to acquire new phones in the coming months, you would think that bouncing a 25 year customer around to 4 different "customer support" each claiming they could help would not make a good first (or lasting) impression.
