Very Poor Service

I have been waiting for the device to be installed in my 2 cars since the 1st of July. The technician gives me a runaround, you can't find him on his cellphone and he's forever not available at his workplace. I reported the matter to Client services but with no help. They keep sending me messages postponing the installation dates. I can't use the car outside my town or at night as I am not covered as yet as my insurance is waiting for certificate.
