bad bad bad service

I bought a car last year june and was instructed by the insurance to install the unit.I installed the unti and ever since that day it has been having a problem. I went to the alberton branch to have it fixed and the said it my battery.I bought a new battery but the problem continued. I went again to the branch and the technicians were too busy and was asked to come back some another day.I work shifts so I don't have enough time during the week.Some time in December 2013 I called the call center to check the unit if its tracking and was told I will be sent an email but I am still waiting.last month I went to the branch at 8h30 in the morning I dropped the car and was told to come back later.At 14h00 I went back to the branch and my car was never touched and was told the technicians are not enough. I was not happy I spent the at the mall hoping that my car unit will fixed Haaaa ! im still waiting .Sad part is I am paying for this every month.The lady at the branch said she will arrange for someone to come to me and have the unit fixed guess what its been weeks and I am still waiting .
