Unacceptable!!!

A booking was made via your web site to install my DQ track unit. I did receive an email conformation for my booking. Secondly I received a sms reminding me of the booking for the 18th April at 09h00. I made special arrangements to go to work and left my vehicle at home for the installation only to be notified by my wife at 11h00 no one pitched to do the installation. No prior notification from any person that it cannot be done or needs to be cancelled. I am currently being charged for a service that I do not have use of. If the unit is not installed \at my work place in Cape Town"by the close of business on Monday the 20th April 2015 I will seek legal advice with the cost for Discovery and cancel my total insurance policy with your company.
