Victim of cancellation #win

I am being ignored buy Adt security for 3 months now. I joined adt over 10 years ago been a loyal client and loved their service. The day I decided to cancel due to financial problems I am now held responsible and being to to pay for all my equipment they have installed. Tried getting a manager to contact me to no avail all they want is their money which in the contract doesn’t state that equipment will be asked back only radio link. To date not a single call only calls and sms’s for money
