I am bombarded with spam a few times a week

Vodacom I have my current contract number for almost two years now. I have been getting constant calls and sms`s from debt collectors looking for Mr de Jager a person that I do not know. Besides this I am constantly bombarded with competitions, insurance adverti*****ts and multiple other spam messages.<br> <br> This is unacceptable I did not authorize you to share my number with any company for marketing or any other purpose. This is a serious breach of my privacy and is really frustrating. <br> <br> Please resolve this, I cant take it anymore
