Shocking Disgusting Customer Service

A couple of months ago I had NETSTAR tracking units installed into 4 vehicles (Toyotas). The first time I tried to turn on the wipers on my Hilux the wipers did not work, I thought it was an issue with the car. I took it to a workshop, after striping the cover where the wiper-motors are located we found the unit installed there, it was loose and obstructed to wipers. I asked my wife to check her Fortuner and my father to check his Hilux. None of the wipers worked!!! If we were traveling on a highway and it started to rain, this would have been a massive issue!! I also removed 2 of the units and did not even get a call from Netstar?!?! After a massive fight and Netstar wanting to charge me for deinstallation THE DEBIT ORDER IS STILL GOING OFF EVERY MONTH!!
