complaint

I phoned vodacom customer care to find out where does other people get my number,because I am getting smss and email of people I don't know,and its a lot of companies sending this,asked riana where people get my number because its very irritating,and told her that I think its people from vodacom that give the publics phone numbers out and she put the phone down in my ears,if phone vodacom now to select I get xhosa or zulu language to choose from,don't understand that language I asked to speak to a manager then they give you a teamleader to speak with!that is not what want!service is POOR!
