Renault tracker issues

I bought a car in February at Renault Oudtshoorn, The dealership did not tell me there is a tracker in the car, a few days after purchase I received a message from tracker them self stating that my tracker is active and the certificate is send to my email I received it without knowing it is going to cost and extra 355.60 Rands I wonder till this day how tracker got hold of my account number because when i bought the car it was never explained to me that there is a tracker in the car and that its gona cost extra, I never wanted a tracker and I never wanted to give out more money than i had to, very dissapointed in the service
