<prompt> Human: So, this all started when I was working on a military base, and hooked up internet for all the guys in my mod. They paid me, and I would go and pay the bill at the end of the two months -- simple stuff. Come the end of the two months, I go to my local ISP shopfront to cancel and pay. Upon doing so, I learn that the store cannot physically cash in a payment for the account, much to my chagrin. I learn that they are only there to sell iPhones and hand out modems. So, they pointed me to a phone off to one side of the store, and told me to call Customer Service. I do, and the guy on the line says that he can transfer the down-payment I made on the account to pay the majority of the bill, and I can just pay through my bank upon returning home. Simple and easy, finally. So, I drive home, and log onto my electronic banking to make the final payment, somewhere along the lines of 10. Thats when I find out I cannot pay the account off, because I do not have any actual account information, and no matter how hard I try through customer service, they cant find it either. So, fast forward a couple of months, and I get a call from the ISP, saying I owe almost 7 times the initial overdue amount. I try to get the essential account information, such as a phone number or an account number to no avail. I cant let this stupid account eat up money, but I have no way to actually pay the damn thing. Any way you can help me out PF? TL;DR: Bell Aliant cant find account , so I cant pay the account. Edit: found the initial number that called me and found its a collections agency. Will call them up to see where we can proceed from there. Do I try to pay off the overdue account? Or fight it since there was no way I could access it?Thanks for all the help thus far  <response>: Huh? If they cant find the account, then how can they prove you have the debt? This makes no sense.Call them and ask for a letter verifying the debt, as they are required to do under the Fair Credit Reporting Act. It would have all of the account information.
