PTI Security Systems

I have had PTI for about 15 years. They were very good in the beginning but have grown worse every year with support. We are down and submitted a support ticket 30 days ago with no response. We have called 5X with no return call. We contacted the salesperson 2x who has submitted escalation request but no response from support. I would highly recommend them to all our competition.... Out of desperation, I wrote the PE company the owns them, the CEO, and put in another support ticket. Finally, the next day I received a contact from customer service. We resolved the problem that day. Worked well for a month and went down again. As their MO, we put in a support ticket 3 weeks ago and haven't heard a response. This company has the worst customer service I have ever seen!
