CODACOM VERY BAD SERVICE

Hi, app**** for a upgrade on my 1 contract, 5 days ago, now i have phone every day since trying to get an answer and spoke to about 6 people some even drop the line on a person, no one helps, now i have no idea who I have to beg for a reply, they get every thing wrong, everyone give me a different reply, so how do we deal with this incompetence , as Vodacom is really unbelievable, and now one can help and i must waist my time calling only to get now help at all. really PEOPLE should not use Vodacom they are really not worth our money they should be investigated , as for the staff dont they get training. sis I am really upset now even the CEO does not reply to the mails..
