No Marketing Consent yet they still call

I have now received 3 calls from Cartracks telesales team. Yesterday afternoon while i was driving at around 16:00, this morning at 9:44 and on both those instances no one talks. <br> <br> So this morning at around 10:00 - I call the number and it diverts me to Cartracks reception and then a lady in customer care who promises to put my number on a DNC list.<br> <br> Lo and behold it is 10:51 and Komotso calls me from Cartrack to sell me a tracking device. <br> <br> 1. I have never given Cartrack marketing consent. (Breach of CPA)<br> 2. I have asked you not to call me again. 3rd call is now bordering on harassment<br> 3. Komotso on a voice recorded line says they got my contact details from Transunion. So is he now alleging that Transunion is selling my personal data. ( Breach of privacy)<br> 3. If I receive 1 more call I will be exercising my rights!<br> <br> Cartrack needs to train their staff on proper telephone etiquette and the 9 Rights that a consumer has relating to the Consumer Protection Act!
