Ongoing Unhappy Client

Very Unhappy Client. I have been a client with Car track since I think June last year. We decided to get the dash cam about 2 months ago. Since then I notice that the Camera didn't work, They fixed the issue but then I Noticed that the camera doesn't switch off when the vehicle is switched off. After my vehicle stands for more than a day i noticed my vehicle take longer to start than usually. I requested them to have a look. Received an email stating they will book a technician to come have a look. but days went by no one came. Me vehicle stood still at home for 2 days, the next morning I had to jump start my vehicle as battery was totally flat. I eventually went straight to the Rustenburg Office they checked and reinstalled a new device. But problem persist. Battery is damaged and i need to charge it every night just to not struggle in the mornings as I need to get to work in time. I keep communication with Wayne if I have the name correct. According to him on the system every shows its fine but how will my battery will become faulty just after the dash cam was installed. Car track told me that I will have to pay for this fault findings, but how is this my fault if I asked for help on this matter. If i knew this will happen i would have never gotten the dashcam in the first place. At this point I am not satisfied with Car track at all. Vehicle is in for a service today. I asked Nissan to also Check if they can assist with finding what the problem is with the battery as the battery is actually still new. We got a call Last Friday from Them after the review, But the never called back again. So I am still struggling, But they want their money but you as client have to wait for service.
