Poor Service

I installed my unit and initially opted for a 99 Rand option, someone called me to upsell n upgrade it 2 a 149 Rand option n one of the feuteres was to notify me whenever there is unauthorised movement on my car, I've removed my battery several times and nobody called me from car track, I called them on the 1st and the lady i spoke to advised my unit was faulty and they will immediately book a technician to come and check it and still nobody called me or came, I phoned them today n they said there was a delay n nobody cared to inform me of the so called delay, am considering cancelling dis thing n go somewhere else.
