VERY POOR SERVICE

VERY POOR SERVICE! I am trying to add a new vehicle - after not getting any call back from a Netstar representative called Namelle. I've called twice and was told to hold the line, after holding 25 minutes, I get cut off BOTH TIMES!! HOW DO I ADD A NEW VEHICLE AND GET THE NETSTAR ACTIVATED?? It already has unit fitted to it and I am taking delivery of it on Saturday. I need someone to phone me to activate this or I will be taking my services to Tracker.
