Make appointments and don't arrive or follow up

Twice i have arranged for DQtrack installation. Twice the installer has not arrived. The first time I at least got a call an hour and 15minutes after the appointment (I was the first appointment of the day - 8am)<br> I had arranged the second appointment 10am today - with Vinesan Phillips (operations manager). He said he would follow up and ensure they arrive. He did not follow up as per notes on system. I have been on the line to the call center since 10-40am. i am unable to speak to Vinesan. The call centre will not transfer me to his superior Shana Gorumbe. They will not even give me receptions number let alone Anton Ossip's pa number. they will reschedule for 1pm. i am self employed and don't work consistanty in an office. I am now waiting for complaints department to call me as they don't have a direct line as well as for Vinesan. Vinesan will decide if he will escalate this upward to Shana or Anton. I still have not had a call from Vinesan.
