NET STAR POOR CUSTOMER SERVICE

1) after being told insurance policy is nul and void if there is no tracking device, Netstar take two full weeks to install tracking device. vehicle was collected on 11 October 2018 and installation was carried out on 26 October 2018. 2)They send out a technician that pulls almost every panal out the rear end of my vehicle to retreave the "old" unit and then removes it and takes it back with him as "company policy". 3) Since this day, my windscreen wipers have not been functioning properly. when you push to wash the front windows the rear water sprays but front wipers activate and visa versa, when you push button to wash rear windows, front water sprays but rear wipers are activated. 4) Then at month-end , all of 5 days later, my first invoice comes through and i have been billed for two additional artime amounts. when i queried it the accounts department said tehy would reverse the amount. 5) Netstar send out a "more" qualified technician only to tell me that he cant sort out the issue with my windscreen wipers as the "his previous technician" would never have opened anything to do with the water!" once he had left, my vehicle now has a problem with its cooling system and keeps complaining that the cooling fluid is low!!!! 6) a month is now gone by, no account reversal have been done and yet again Netstar have debited amy account with a wrong amount!!!
