So I get a bill in the mail with a credit balance of about $65. No phone numbers listed on the bill, and the account number is different from that of my current account. I call in to inquire about the bill. Turns out it is from 2002!! I closed the account with a credit balance, but apparently it never fully closed in their system and I obviously forgot about the whole thing. So I got the credit balance shifted over to my current account and all is well. You think it would have taken Sprint 5 years to bill be if I owed them money??
