Carrier/rack problems of the 2007 Chrysler Aspen

It's a tracker on my truck and the dealership isn't using it properly. If my car payment is late then yes, I know it's supposed to shut down, but if I'm making a payment on time then why it keeps shutting off in the middle of nowhere. Been late for work, school, and picking up my 5 year old from school. By the way she is going to be stranded as we speak. Made my payment on 9/18/17 now it's off today. Made my payment last Wednesday, and I had to call them Thursday because it was off. Last week they turned it back on after I told them I'm making a complaint with them, now they don't know what the problem is today. It's the same thing from last week. The guy turned it on last week but he seems to not know the problem this week. I can't keep affording to miss out on school and work, and for surly can't keep my daughter from getting to and from school. I asked him to turn it on today and he says it's not them everything is brand new in my transmission/motor and my battery works just like last time. This is the fourth incident this month. He also told me he can see what the problem is, but I will have to pay for the tow. I am a loyal customer that got a car from them last year. This is not my fault they put a tracker on my car that keeps shutting off. Please help me!!!!.
