Worse Nightmare & Bad Service

Frustrated and angry due to the poor service of this tracking company. For months I've been trying to contact them so as to cancel this service. Eventually I resorted in using their what whatsapp number. Firstly when I asked about the location of my car just to check whether the device was working....I was told that the tracking device on my car had the low battery and it was required to be change as It's couldn't locate my car. To my shock I then send them the cancel my contract same time but they only responded to my email in two weeks. The same I request another tracking company to install a new tracking as I was so scared to drive my car without a Tracker. The following month I started reverse the debit order to them with continued for about 3 months. Currently my account with them has been handed over to Credit Bureau due to non payment. The payment for the device that was not working and no one was interested to inform me.
