Well my 2 cents worth. I bought my alarm new off eBay 5 years ago and Only had one issue which if I had read the manual would have been sorted on the spot. I'd be forgetting about the alarm and starting to focus on offering some constructive advice. In fact I agree with the comment about the alarm actually being a symptom of an electrical issue.
My gut feeling is, the dealer needs a kick Up the ar*e, pull his finger out and fix the faulty electrical component rather than just twirling the revs knob. It sounds like you're not being looked after and your issue should have been sorted already.
Stick in there and try to not feel like throwing the baby out with the bath water, even if you do feel let down. In the big picture this is nothing even though it doesn't feel that way at the moment.
