DQ track technicians and no service

I haven't even started a full month yet with discovery and have encountered numerous problems and lack of service. I booked an appointment (Friday 23rd October) for a technician to come and setup the DQ track in my car, they even phoned me to confirm the time. No one showed up, i called discovery and was told they would call me back with an answer, never heard back. Called back again same day to ask whats happening, again was told they would contact me...still no one called back. I called back a third time, booked another appointment for the technician to come and install...again they didn't pitch up. After calling back and speaking to the supervisor (Ashley) he organised for DQ Track to be dropped at me. This was done. I then have been trying to install the device but it won't sync with my phone...I have phoned 3 times to discovery each time someone else telling me to do something different which I duly do and it doesn't work, the last time I called back I was told by a supervisor that they see the problem and will call me back within 30 minutes, am still waiting f. This is the worst service I have ever experienced I expect a full explanation ASAP as to why this happened
