Cartrack charging for a tracker no longer on my car

I called car track over a month ago asking them to change my tracker from my then current vehicle to my new vehicle. I informed them that im swapping in my vehicle for another one and that it will be on sale.

They informed me that Car Track Scheduling would get a hold of me. A week passed, I called cartrack to find out what was going on and they transferred me to "Cartrack Scheduling" which kept me on hold for 15min until the phone cut automatically.

I called again 2 days later and the same thing happened. About a week later the car sale told me that the car had now been sold and that I needed to get a hold of cartrack so they remove the tracker.

I called cartrack and they said Scheduling department would call me. Nothing happened. The car was sold. I contacted cartrack last week trying to find out what was going on only for them to tell me that Cartrack Scheduling will call me.

I am still paying for that account via debit order for a tracker I dont have. It now has been 5 weeks with no service from Cartrack in that regard.

I am really disappointed in the service that they have given me
