Cartrack not a loyal company
This company gives clear evidence that client loyalty is not appreciated and loyal clients are viewed as dumb schmucks just there to be ripped off.
I had a Cartrack "Quick Executive Plus" unit installed in my car in 2008.
On installation I was told I would have: vehicle recovery, control room response, on line tracking, power event notification, cross border notification.
I am currently paying R195.30 per month. 
Their current entry system at R99 per month would give me most of the above.
What I am getting:
Their online system does have my vehicle registered I cannot track my vehicle
No notification of power events
No notification of battery disconnect
No notification of border crossing
I do get a notification they have tested my Unit once a month
So they are happy for me to pay double what the current going rate is, 
If they are prepared the treat me like this how sure can I be that they will even try and find my car if it is stolen
