Assistane

I sent an email to Cartrack on Monday, as well as contacted them telephonically, reporting that they should please revise the installation of the tracker, as it is pulling power from my battery,causing the car system to trigger an check system error message. I explained that i use the car daily and was left stranded twice with no battery power. Only to be informed they can only assist me on the 21st May, not taking into consideration the fact that i need the car every day and how dangerous it is for a woman to be stranded along the road. Payments are being recieved diligintly every month, if i had to request for a new tracker, a technician was going to be available same day, how come not available for maintenance or review?? I was told i will be informed if their would be a cancellation, to date i am still waiting. I am very perturbed and dissapointed and find cartrack not helpful in this situation. I have to discnnect a battery terminal to ensure that i can be mobile in the morning, only to get an error message when i am on the highway and then driving to work in fear. This is so unacceptable.
