Unoffiraiced payments

I have bought a car from a dealership.The dealership told me that the car is fitted with a tracker .I told them not to activate the tracker I am not interested. They agreed the next month Cartrack was taking a payment.I reversed it and call Cartrack to ask them ho give them permission to activate and take payment.They said I have sighned papers at the dealership to activate.I must pay a cancellation fee to cancel .I told them to send me a copy off the paperwork then I agree to pay the fee.I also went to the dealership to asked what is going on and they confirmed that they never activate the tracker.Cartrack told me they would send me the copy of the paperwork but never did after a weak they phoned again for payment as I told them again please send me the paperwork to proof that I give permission but til now stil nothing and yesterday again they took a payment out off my account is this how they do business. Activate their system without permission and then force people to pay for their decision.That is why I told the dealership not to activate in the First place
