Cartrack Call Centre

I have been called no less than 8 times today and numerous times in the past by Cartracks universal call center, this is becoming harassment and unacceptable. I need to work and all day I get these calls. Contact number ***. They won't tell me where they got my number from and when I ask where did they got my number as per the Popi act, I have the right to ask and they are forced by law to advise, they drop the call in my ear. This is not fair you guys are gonna cost me my job and I feel like you are encroaching on my Rights, I need to keep my phone on loud I have small kids in school but this isn't right. 1) please tell me where you got my number and 2) please remove me from the list.
