Cartrack worse service ever

I have installed a cartrack tracking system in my brand new car in June 2020. In May 2021 I needed to replace my car battery as it was completely drained. In June 2021 again the car battery was drained I was advised that I need to look at the tracking system as it was the cause of it. A technician came out and confirmed it was fixed. A month later again I'm sitting with a drained battery. After 24 hours being stranded still no assistance was given or maintenance appointment booked. After phoning back I was informed they will phone me back the same day several hours later I've phoned back and requested the contact to be canceled as I'm not getting any assistance. They promised that the appointment is made for 10:30 the next morning. It is 13:00 and still struggling to get proper assistance.
