Confused, unhelpful staff

I got a call from Tracker to confirm the cancellation of my unit. I can't believe how *********** they are!! I didn't request a cancellation. They cannot give me information and want to cancel my vehicles tracker!!! They said they will get back to me as to how they got an instruction to cancel my unit, but up to now they haven't. What is wrong with tracker staff? How can I entrust my vehicle to their care, if they are so ***********. Will they ever be able to do what I am paying for - iow to retrieve my vehicle in the event of a theft, if they cannot do a simple thing. Now that they have cancelled my Tracker without my authorisation, I hope that they also refund me all my money. I will apply now to get a Netstar unit fitted today onto my vehicle. I am sick and tired of Tracker's incompetence.
