At the end of June Sprint sent letters to customers who made an unusual number of calls to customer service, giving them a month to find a new carrier. These customers were making an average of 25 calls per month to customer service, where as the typical Sprint customer calls once every 2 months. The letter went out to approximately 1000 subscribers, though earlier reports estimated the number was much higher. This is still an unusual move as no carrier has ever canceled subscribers in bulk like this before. No other national carrier has canceled accounts because of the number of customer service calls subscribers made, however Verizon admits to canceling the accounts of individuals who were extremely abusive to customer service reps in rare cases.
