Netstar Useless service

We have being loyal customers since September 2012, with Netstar fitted to four of our vehicles. The contract ha since long ended, but we continue month to month. The other day, one of our remotes had stopped working, and upon phoning Netstar, they told us that the units in our vehicles are old and discontinued, and no parts or spares are available for them.

1. Why did they not inform us when the systems were discontinued, and give us an option to upgrade to new systems? 2. What if these systems failed to work, and one of our vehicles got ******/hijacked, and Netstar would be unable to track it. Our insurance would fail to pay out, as it stated we have a tracking device. Would Netstar pay out. 3. These units, being old now tends to drain the batteries of the vehicles if they are not used for a few days.

This is really pathetic service from Netstar, so we will be looking for a new supplier.
