Never use Fidelity ADT

This is the worst security company ever. I have used them for 5 years, never called for armed response once in those 5 years, and now I want to cancel as I have been ****** and ADT is useless. I paid for this alarm system and now they want to remove it, claiming that it belongs to them. I have requested m contract and a copy of the invoice I paid when I joined to confirm who it belongs to. It has been 4 weeks and I have had to call in multiple times. They are dragging their feet on the cancellation while I sit at home and get ******. So now I cannot do anything until they give me a copy of my contract, that I requested 4 weeks weeks ago. I am sitting in a house with no alarm system and the inability to upgrade, leaving me at risk as I have been ****** recently and want to switch to another company. I cannot upgrade the current alarm system until it is confirmed who owns it. These people are ***********.
