Poor call centre assistance and damaged goods

I have had a tracker with altech since February 2012 fitted on my vehicle. In February this year, the unit started draining my car battery, and I called Altech to have the unit fixed. Since the 3 years were up, I was asked to sign a new 3 year contract and a new unit was installed in February. A week post installation, I have had endless hassles with the tracker not activating/deactivating on the remote, panic signals emitting every so often.<br> <br> Tracker contacted my Dad, and sent him into a panic that my vehicle might be ****** because I didn't answer my phone. They failed to mention that the entire week the panic signal had been emitting.<br> I have lodged numerous complaints with the emergency call centre and the customer service centre. Ive been promised that I will be contacted and an agent will be sent out. Finally I was attended to yesterday. The remote beeped in the technicians presence, I signed the documents and he left. By the evening, the unit wasn't working again.<br> I contact the call centre AGAIN today, over half an hour of being pushed from person to person, and finally they agree to send out a technician. WHO then goes to my HOME address when he should have come to WORK.
