<prompt> Human: Back in September I opened an account with sprint. The service was horrible so I closed it within 30 days. I returned both of my phones to a local sprint store and they gave me receipts documenting this. Now Sprint sends me an email to pay the balance of one of the phones. After going into the local store and calling customer service its revealed that the issue is the store never provided documentation to sprint corporate that the phones were turned in. So they are sending me to collections over their error. They refuse to remove this from my account and I wait on hold 30 mins at a time. They also refuse to escalate my issue. How can I get through to people who actually give a damn at sprint? EDIT: Update Here  <response>: Make copies of your paperwork and go back to the store. Try to go during a time that isnt too busy, and make the store employee call. Be nice about it, but its their fuckup, so they need to help you fix it. They may or may not have a phone number that bypasses the crappy service.Also, dispute the collection on your credit reports. Scan in the paperwork from the store for proof.
