Tracker: No response, no reaction = NO CONTRACT

It would not surprise me if Tracker has closed its doors as there is absolutely no sign of life other than the automated invoice that arrives in my In Box.<br> <br> For the first 6 months of having Tracker in my car, I received faulty / false signals and reported it whenever I received a call. The last call was quite a while ago and, despite them saying that they would get someone from the technical team to attend to the problem, nothing happened.<br> <br> I have then requested cancelling my contract on a number of occasions and had no response. My last request dated 2 July received an automated acknowledgement of receipt response via email but nothing further.<br> <br> I am (a) not happy that Tracker seem to have gone to ground and disappeared (b) their customer service is non-existent (isn't that what I am paying for?) and (c) they do not respond to customers.<br> <br> I would like it put on record and I am now cancelling my account with effect from end of July 2015 - do not send me any further invoices.<br> <br> <br>
