Netstar - Horrible .....

I am a long standing client with Netstar (since I have owned vehicles - 2009 or so). I am currently experiencing issues with the tracking unit/s that were installed in my current vehicle since 2019. It is draining my car battery (which i replaced a few days ago). I am currently on a month to month with Netstar and they will only replace the unit/s if i take another 3 year contract. In addition if i want to cancel i have to still place another 30 days notice which means i have to pay another months subscription at the end of October 2023 and let the defective unit/s drain my brand new battery until then??? I need someone to assist me urgently.
