I'll list them:
1. units weren't updating, took Matrix over a month to get units replaced.
2. Truck got stolen, unit removed from truck in under 10min, Matrix told us nothing they can do. Never send their retrieve team to the last known position or anything.
3. New units are installed in a day, but de-installation or replacing of units will take over a month and you have to constantly phone and hassle them.
4. We upgrade with Matrix to MIX3000 units, the new units they put in were never properly tested and we had only 1 unit out of 20 working at any point of time. They tell us we need to sign new contracts and upgrade to a new unit they released.
5. Even the "back up" units in our trucks don't work. So if a truck gets stolen, that's that.
We pay around R300 per month per vehicle, and the unit is only working once a month or so.
