Debt collection — Perfection Collection (AZ)

Threatened to sue you for very old debt. XXXX was to install equipment in my house and never did. I called to cancel and the bills just kept coming. I faxed them and mailed them as you can see from the files I have sent. They just kept sending bills until the amount was around XXXX dollars. The bills did stop but turned over to a collection group called Perfection Collection. They have made many threats not only to me but my wife and son who dose not live at home.
