Failed to communicate

No communication whatsoever. Date and Time was booked 7 days in advance just to find out 1 hour later from initial time booked which I had to then contact them to find out where the technician is just to find out there are no stock in there dash cams. My problem is'nt that they dont have stock, but waisted almost 2 hours waiting for this guy with no one coming back to me. Really bad service.
