I now need my broken tv

Bradlows took my tv in for repairs 2 years ago and never heard from them. They told me they can not repair my tv at all.I have since stopped paying the instalments because i cannot pay for something that i do not have. Black and Associates lawyers call me everyday about this account and they need me to pay WHY SHOULD I PAY FOR SOMETHING I DONT OWN. I went to their shop to tell them to return my broken tv and theyve told me they do not even have a clue were the tv is.Bradlows please give me back that 50 inch broken tv that you said can never be repaired, or give me another tv to replace that one or else stop calling me and stop threatening to blacklist me. You took my tv and never returned it and you still need money from me???..
