ADT sucks after I've moved to new location

December 2019 I moved Into a house bought. ADT used the existing equipment and just activated it but I needed stuff moved around and sensors on all the doors. After 6 months no one has come after multiple appointments.

Around October I spoke to someone claiming to be the regional sales manager. He came and did another assessment and promised to sort me out. After weeks of hearing nothing I tried making contact to no avail.

Today more than a year later I've had enough. I don't even have a code to arm my system which completely defeats the point. I phoned ADT and explained everything which she was clearly shocked by and said I need to speak to complains. After holding for a few minutes she came back and said no one in complaints could help me but they will phone me. I'm still waiting for the call.

If anyone can help me on how to take this matter further to something like an ombudsman to get this canceled please comment because I've had enough now.
