Conns Billing wrong to me and credit bureau Thornton Colorado Nationwide

Oct 17th 2015 my husband and I went to the thornton 102nd conns. We made an order that day. It was due to deliver oct 24th. We called the 1800 number to cancel it on the 21st of oct. This amount was over 7000 dollars. We were told it was handled and canceled. Not realizing we took 3 bed covers a king twin and full. Which total 271.22 Which we have never received an accurate bill for ever. In November I was contacted saying I owed 3123.77 which is different then the many amounts this company has sent on statements after mid november. I have called and spoke to managers and many others of which all of my calls have been recorded since day one of them telling me in oct our account was handled and closed. Well now they say we owe over 900 dollars which isn't even possible even if you add the late fees which shouldn't be there because if they had billed us correctly we would pay the 271.22 in full but they can't seem to get it right. Anyways we are now in feb 2016 and they have reported to my credit hurting my credit over their mistake. I plan to make this known this company is not only unprofessional but very unreliable. I owe 271. 22 I have statements from the store to back up how bad this place is. Please don't go there I promise it's not worth the chaos. My family is having to go through hell all because this company we have faxed the paper work we got directly from the store and it is enough proof. All we want is to pay our 271.22 and get confirmation this account is closed and get it off my credit. I can't believe this company is even still open because they don't communicate between departments and they have collectors whom are very rude and inconsiderate. They harass your phone every hour for money you have proof you don't owe. I hope it gets handled soon. I'll be writing reviews everywhere I can and reporting to the bbb. This is unfair by all means.

Desired Resolution: Billing Adjustment Desired Outcome I would like to be able to pay the correct amount which I have a statement from the store that has been faxed to their departments. The amount is 271.22 with a email and mailed copy that this is closed and I can send it to the credit bureau since they have affected my credit. I just want to pay the amount I could have payed right away that I rightfully owe and not have late charges or fake amounts for products we never had. I'll send a fax or email of proof of what I actually I owe I got from the store itself from the manager I just want this off my credit and never to have to deal with conns again. I'll appreciate any help at all.
