Extremely frustrating!

I wrote a review about tracker recently. I have been trying to sort out my device which is faulty (working inconsistently according to one tracker technician ). I have had several ppl try and assist and I have been told it now needs a technician to evaluate it. I really battle to get through to tracker on the phone lines. I even sent a msg on the tracker web to say I would cancel my membership as I thought it might assist in being helped but I haven’t been contacted. The last contact I had with tracker was that the case was open and that the team who sets up a technician would contact me to arrange an app but that was a week ago and I have not heard anything and when I try and contact tracker I can’t get though!
