Terrible Service , Broken down vehicle for a month

I had tracker installed in my vehicle in January 2016 , ever since had problem with the ignition which i never experienced before. One evening the vehicle refused to start. Had the vehicle seen to and was advised that the tracker technician would come out as well, of which they did and took pics of the fuse box that was blown. According to the technician at that stage when i spoke to him on the phone he said it does look like its tracker related.The vehicle is now laying at the Toyota Dealership and i have had no car for over a month. The toyota dealership updates tracker however tracker with promising to update me never come back to advise as to what is going on. I have been pushed from pillar to post and cannot get an answer. My question is , if this is tracker related what is the problem , why is my vehicle not being fixed , also the part that has now been affected is only available to the dealership in JUNE. What happens to me in the interim. I cannot accept this kind of service and demand that tracker provide me with a courtesy car until then as the mistake was theirs.<br> I would like an answer ASAP.
