T Mobile continues to ignore the importance of World Class customer service. This is reflected in their continued failures according to JD Powers rankings. Where T Mobile reigned supreme it now wallows in obscurity. It all began when T Mobile transferred its customer service centers to the Philippines for Prepaid Customers and later opened a call center in Argentina to serve Spanish speaking customers. With the failed sale of T Mobile to AT&T and the subsequent closure of 1/3 of their customer service call centers in 2012 (and prior gutting of experienced staff), a practical, obvious absence in real customer service was sealed after a 3 year behind the scenes decline. It will be a long time before T Mobile can be said to have World Class customer service.
