tracker installation not done . booking postoned t

Initial appointment was made I December 2014 for Jan 14th 2015. The technician cancelled with me as he couldn't do the installation in a car ba*****t . I made the second appointment myself in Early Feb and the 28th Feb was confirmed for installation to be done at my home. Today on the day of installation the technician is a no show, and nobody called to inform me of any delays. I called discovery my self and got no solid answers .....just got attended to by an *********** person that isn't solotion s driven. I requested to cancel my insurance and I was told that the cancellation department don't work on weekends. I was further advice that a QUERY has to be logged before I can cancel my insurance. That laughable because a query wasn't logged when I took out insurance. I want someone to call me and help me cancel this by end of day Monday 2 March
