Letter to CEO in the mail, I tried a final several calls to SprintPCS to resolve this. First time: Transferred to what appeared to be the voicemail of a warehouse that processed bulk orders for corporate clients.
Second time: Request to speak to a supervisor results in being disconnected.
Third time: Request to speak to a supervisor results in being sent to their Corporate/Business Early Accounts unit. Luckily, the rep there was the only person who was moderately helpful in the past few months. Still no resolution though.
My advice: Stay away from SprintPCS if you want the miles. Customer support sucks.
