Paying for Items not Received.

I have an account with Homechoice and lately been handed over to their attorneys for items I have not received delivery of. I have been in diputes with them since last year and no resolution has been made to amend this error. I am charged for items I have not received and submitted the required documentation. I went above what they needed to trace the courier company and obtained the waybils, signed by other unknown recipients, and submitted all as required. They persisted in charging me interest for items that I paid off long ago and taken me to their attorneys and affected my credit scores.
