shoddy service from Tracker.

I have been a tracker client for more than 15 years - I sold my car on 29 September - tried to call them to advise them on 29 Sep - eventually gave up and send message on App. only reverted in first week of October which meant I am paying for a service I don't use and had no tracker on new car - the car is still being tracked for some other person. first they told me to give a month's notice to cancel - who knows a month ahead that you are buying new car on a particular day. then I reenter into contract for 3 years on 4th October (had to spend 25 min with the online consultant) - still have not been informed where to install and when I will be refunded my October payment. I wrote to them to inform them I no longer am doing business with them. why be loyal to a company that does not care!
