Vodacom assists spammers

This is something that really should be exposed nationwide. Companies like Vodacom hide behind a veneer of respectability when some of their business practices would be better suited to phishing ************. How can I say this with cer*****y....well because I have incontrovertible proof. About a year and a half ago I took out a data contract that included a Samsung tablet. I have no idea what the cell number associated with this contract is. Thus I have NEVER given anyone this number...I don't even know it myself. Yet within a week of activating this contract the spam smses started. Then the phone calls from direct marketing call centres. At this point I am inundated with smses from SABC tv licences, Hollard Insurances and a multitude of funeral policy and loan companies, some of whom address me by name. So my question to you Vodacom is how did these companies get this number if the only people who know it are Vodacom and myself
