bad service

i had a dashcam put in with cartrack.Then all of a sudden it stopped working i couldn't track my wife it says data is up i must load.I didn't know how or where to load data and how much it cost. They just installed camera and left,my wife drives a dangerous road famous for hijacking and smash and grab. I mailed them and explained this and asked them please to explain to me how and where i load data because nobody told us nothing. 6 days later and 4 e-mails they still didn't make an effort to contact us and explain,and my wife is driving like that to work and i can't track her. They dont care or worry and service sucks,that is now the camera department i'm talking about
