Worst customer service from the repairs center

The worst service i have ever experienced. Cartrack do not care about their customers All they care about is the monthly subscription. I have reported that their unit is draining my car battery two weeks ago. I am struggling to start my car every day. Remember I am single woman and I am driving an older model car. My car battery is brand new, I make sure that I switch off everything when I pack the car in the evening. I still struggle with the battery the next day. I cannot wait for the contract to end so that I can de-activate their useless unit from my car. Received a call from the car called Mbuso, I have an email confirming that a technician will be send, to date I haven't heard anything from them. I am so gatvol of this company. I have had enough of their terrible service.
