Too Good To Be True!!!

I renewed my Vodacom contract and two days later a consultant offered a cheaper and better option which I accepted as I was in the 14 days cancellation period of the initial contact. I am now told I will revert to my VERY EXPENSIVE business contract from 1 July and can only then change to the new contract? Every consultant I speak to - and I have a LONG list of names and times - has a different variation of the story and the consultant, Dillan Chetty, who suggested the no strings change, is now MIA!!! Conveniently!! I have been with Vodacom since their inception on expensive business packages, but this is the level of service you get when you need to review your contracts and costs!!!
