Late last month Sprint sent out a crop of letters notifying a "small minority" of its customers they were terminated because of excessive calls to customer service. Terminated customers had their account balances set to zero immediately, but Sprint noted in the letters that the subscribers must sign up with a new carrier by July 30 if they wish to port their phone numbers with them. The letter reads:
"Our records indicate that over the past year, we have received frequent calls from you regarding your billing or other general account information. While we have worked to resolve your issues and questions to the best of our ability, the number of inquiries you have made to us during this time has led us to determine that we are unable to meet your current wireless needs.
"Therefore after careful consideration, the decision has been made to terminate your wireless service agreement effective July 30, 2007."
A Sprint spokesperson said auditing their customers in this way is common practice, because the carrier has "to be able to quickly and efficiently serve customers." During the first quarter of 2007, Sprint reported a loss of 220,000 post-paid subscribers.
