Nightmare of a company

The cartrack unit was installed before the car was sold to me by the dealership. But the person who came to switch on the unit tells me that there was not even a unit in the car to begin with and he had to install one. He showed up there without me being informed of when he was going to show up. When I tried to log into my account/app I could not log in. I sent through a ticket on the issue I was having logging in it took them 5 days to get back to me. Then when they sent me the car details all the information was wrong when I sent it through to the company they ignored my email but when the car dealership told them the details were wrong they answered him immediately. I have sent through other tickets which no one still has gotten back to me. I have since then put in a cancellation request and still no acknowledgement. I have even sent emails to the CEO that they have on cartrack's website but the CEO has not even responded. It is less then a week that I was with them and it has been one problem after the next.

I want my Caratrack cancelled immediately and this night mare to end.
