Very very bad Service for the third time in 3yrs

On the 25th September 2015 I called car track to de&re installation on my vehicles, but up until today it has not been done and no communication as to when it will be installed. I called the headoffice yesterday they transferred me to Nelspruit branch which needs to do the installation. I spoke to a lady who promised to get the workshop manager to phone me and explain the delay and actually arrange for the installation today. But no one and I mean no one phoned. My fear is I have had the car for 10 days now , what will happen should my car ****** or I'm hijacked, who is going to pay.its really annoying to have to beg someone to do his/her Job who he is being paid to do. I have heard a bad service from the first day I joined car track, maybe it's about time to move .
