Faulty Alarm

Its almost 2months that I have been complaining about the faulty alarm on my vehicle. Everytime I arm it , it goes off and wont stop until I disarm my vehicle. I have contacted Netstar on numerous occasions and all they keep doing is reset which only works for 2/3 days then back to square one. I called the call centre and requested for for someone to be dispatched to check what the problem might be but have not received any feedback. I have spoken to Daniel who transfered me to Portia who sounded as if I disturbed her from her nap and promised that I would be contacted in 24hours but have heard nothing since. Everytime I contact the callcentre I am being transfered from pillar to post. It has come to a point that I do not arm my car which is A HUGE RISK. How can one trust their assets to be protected by people who dont seem to care and have to beg to do the job.
