Cartrack Non existent service

Got a quote, took out a policy. I received a sms to advise wen the technician would install the device, however he never, arrived after I sat at home the entire day waiting for home. I never even got a courtesy call to advise that he will not be coming or was delayed etc. Upon calling the following morning to cancel, I was told I can cancel, however they cannot send me a cancellation email to confirm. After pressurizing the consultant, I received a sms to say that their contract had been cancelled. Has customer service simply disappeared or are customers just being taken advantage of?
