Tracker not connecting-but no response from Tracker Connect

I have found out that my Tracker unit is not working and was still under guarantee. I requested a technician to come out and check or replace it. The only response i get is if they feel it necessary for a reply a consultant will be in touch. I am still waiting despite sending further emails. I have informed them of my intent to write a report to HelloPeter. They are the worst tracking company I have ever dealt with. I shall be informing my insurance companies of their lack of service and let them handle them as well. I have both company insurance and private insurance so that is two companies who will be informed of their dastardly behaviour.
