Worst Service ever

After paying for more than a year i decided to upgrade my package to the early warning package because the extra features caught my attention, but after upgrading i saw my cars location updated once every 2 weeks and this was concerning for me so i raised a query with them before they fitted my panic button, on the day the installed fitted my panic button he checked the device and said it should be working now and it did exactly until 16:00 that afternoon, so once again i had to log a query with netstar so they logged a ticket to have the unit replaced, this was a waiting game and once again i had to follow up with netstar so that they could finally come out this past Monday to fit the new tracker where i once again had to phone them because my car was showing im in Pretoria but im in Cape Town, so that is finally resolved but now we get alert sms's with no follow up if we dont respond and the F@!#$!@ panic button is not working!!!! i think you must remove your **** from my car and reimburse me for the period that i was paying you because clearly if my car was ****** it would have been gone forever.
