I join car track because I wanted car watch then the consulted give me misleading information.he said I must option for an additional device since I had a main device from a different company and I can add car watch and panic button on addition amount.which I agree and I was billed for two month Months went by and I notice my car watch is not working.then call the call centre and I was told it was not suppose to work in the first place I even have the record of your sells person giving me the information and now I can’t cancel while I did mention the main reason for me wanting car track The person was never charged or had any discipline major for him . I had paid for something that was not working which is unfair
