Stop this nonsense of me owing you

I am so tired of home choice telling me that I owe them money and yet I have not purchased anything from them the past 6 years. Now my name will be blacklisted because of their stupidity. When you call them no one bothers to answer the phone. Sort this out ASAP or I will sue you guys for your nonsense. I owe you no damn cent and you ain't get anything from me, and I am no longer buying anything from homechoice never again
