Discovery insure/ **** tracker

Most horrible service ever! I dont usually get upset about services but this is just next level. They installed a DQ tracker about 18 months ago and about two weeks ago the tracker has been causing/draining power from my Main battery, Every time I call for them to fix I get told they call back and never I always have to follow up, Worst part is the lady says they did see an error on their systems, So why not advise me about it, I have to find out through battery center... eventually a technician arrives to fix or replace the tracker battery which now has made it worse...I burnt my finger trying to jump start my car and burnt my cables out(about the 12th time I've had to jump start so I can get to work and meetings) there is just no work ethic or passion from them...they just dont care and you pay for what... its pathetic, my car has now many errors coming up because of the DQ tracker...
