Vodacom arrogant as ever / point blank refuse to stop sending advertising.

Heading for third month of telling Vodacom to stop sending junk messages from vodacom, data offers, receipt books, films etc I have opted out of everything, I have phoned in i have emailed i have BAD reviewed - still the insist> I get a message that Vodacom will get back to me, nothing happens. I thin vodacom has just decided to ignore me, Nice going - 27 years about, i am done in a month or two, no more of vodacoms arrogance for me.
