Worst service every

Absolute poor service from Netstar. I did a change of ownership for a device that was in my mothers name. I advised the service consultant that the vehicle that had the tracker fitted was sold and I need to arrange for a device to be installed in my new vehicle. This was never done although the debit order was deducted from my account. 3 weeks past before someone phoned me back just to tell me that I needed to apply for a new device. I submitted the necessary documentation to apply for a new device but still no response. When I threatened to cancel the debit order I received a call just to inform me that someone from the retentions department would phone me back. Another week has gone by and still nobody has contacted me to arrange for a tracking device to be installed in my car.
