No Service

A DQ tracking device was installed on my car and on my wife's car in January 2015.<br> <br> I have probably logged 4 or 5 complaining nts with Discovery about this but they just do not get back to me. All I get is a phone call or mail to say someonee is looking at it and that someone will get back to me. Well it looks like someone is on leave becuase nobody has come back to me.<br> <br> My wife's device in her car is completely broken and mine is very inaccurate. Please get back yo me asap!
