FAULTY TRACKER UNIT

I had tracking units installed in both my vehicles however one of the vehicles had distressing issues after the installation one scenario i was with my family and all of a sudden I recieved a battery low sms prompt and the car dashboard lighting randomly starts flickering while driving and the vehicle just switched off and could not start afterwards , at this stage I really thought there was a fault with my car battery which was only a couple months old , I called the the emergency line for battery / towing assistance as I was stuck in a very high risk zone in durban at 11pm at night with my family and I must say the claims call centre agents was not very pleasant, I felt they was very rude and unpleasant as if they was doing us a favour they sent a guy to do a battery test and after 40 minutes a guy came and tests the battery and said the battery is fine and drove off without giving any further assistance I was apalled with the service at this stage especially being stuck with my family at a high risk zone going passed midnight , I then called the help line again and explained them the situation they said they can send a tow vehicle and after a certain km range they would charge me for the tow which caused me to feel even more irate with them and I cut the call , I then took out My tool , poped open my bonnet and then decided to disconnect the battery for couple minutes and reconnect the battery , to my surprise the car started as if nothing happened I then rushed home as quickly as possible before this problem happens again , however cut long story short I did call car track customer service department the following business day and they sent out another technician which came and diagnosed the fault and installed another unit , now the car is normal with no issues and no switching off . The technician who came out the second time service and follow up customer service agent service was a 5 but I can't say the same for the battery assistance and towing customer service , Car track should ensure that installation be perfected the first time as this was a life and death situation that I was placed in with my family and I'm really hoping I don't have a issue with my other vehicle as that's only used occasionally!
