Poor communication

As the user portal was indicating that my Netstar hadn't been tested recently I called the customer care line on Wednesday to test my unit. The call centre person initiated the test and promised I would get a call back within 20 minutes, no call back, I called back in the afternoon only to be told that my vehicle was supposed to be in motion for the test to work. Phoned again on Thursday morning, while in motion, and was promised a call back in 20 minutes with the results. No call back, I had to call Netstar to get the results, the call centre person simply said the unit is broken and I need to get it replaced in Durban where the unit was fitted ( I live in jhb). It is only 7 months old! In comparison my wife has an entry level Tracker in her car, when that unit stopped working Tracker phoned to inform her and made immediate arrangements to replace the unit at her convenience.
