Alliedinterstate won't give information, rude, profanity ans sexual comments Greensboro North Carolina

I received a letter from Alliedinterstate, stateing i owe at&t for long distance. seeing how I have at&t phone service right now,and my phone is still working. How can I owe this money. I called at&t, they have no record of me owing anything. I called alliedinterstate (BIG MISTAKE) and talked to a punk named Mike, I asked for the all the original media on file, biil of sale, original documentation proving I owe at&t this money, and the account number from at&t, since they say I don't owe anything.

Mike stated he doesn't have to provide anything other then the creditors names. and demanded payment, when told without the requested information I wasn't going to pay anything.

He began using profanity, and told me he didn't care where I got the money from, to go strape a mattress to my back or get on my knees in my trailerpark, to make the money.

(I did sent a letter requesting the information and for them not to call)They still call, they have called me at work, what if anyting we can do about this. thank you
