Database - DMASA (Do Not Call Again)

Personal Information Breach: My question to CarTrack in Kwa-Zulu Natal is, "Where do you get our numbers from?" - please teach your sales agents about the Direct Marketing Association of South Africa (DMASA) and that when asked the question "Where did you get my number from" not to mention DATABASE. What database? I was called by a very rude sarcastically sounding agent by the name of CAROL. She does not have patience when speaking to her so called customers. Now back to my issue, please do not call me again or I will take the matter further.
