Disgruntled and unhappy

The service i have received from Netstar thus far regarding the removal of the tracking unit from my vehicle has been a nightmare to say the least. I have called numerous times booking a date for the unit to be removed over the last 2 and a half months. I booked an appointment initially for 28 March2018 with no technician arriving. I called numerous times thereafter requesting feedback and was told i would be called back, which didnt transpire.The last call received from the service centre was on Tuesday 24 April 2018, i confirmed an appointment for Thursday 26 April and for the 2nd time no one pitched. Please arrange for your unit to be removed as you are delaying installion with my new service provider.
