Unauthorized cold calling

Cartrack, please explain to me why I've never googled you, never opted in to anything, never requested a quote from you or had anything to do with you, yet somehow, you constantly phone me from an automated system so a computer can try to sell me a product I don't need or want? Where did you even buy my contact information? I'd very much like for you guys as well as whatever company gave you my information to both be fined and held accountable for the constant flow of spam calls.
