Pathetic service at Vodacom

The service we have got from Vodacom is actually Pathetic. I got a call from someone at Vodacom call centre saying that for just an Extra R200 a month on my current contract I can get cheaper call rates to call overseas. I agreed to it. My bill in April showed that my contract was migrated, I lost my subscription discount of R635.40 which was never communicated to me on the call and I am now paying an extra R900 a month on my contract, if I knew that was the case I would have never allowed them to add the extra R200. Since I received my billing I have logged multiple calls (first reference A2-F***-4IC1RR) I was then told to go into Vodacom to pull the recording, which was a fail as they couldn't get access to the recording (reference A2-FK70-5WPUT). I am soooo fed up with the service of Vodacom that I am on the verge of cancelling all my businesses cell phone packages. Vodacom is so easy to deduct their monthly amounts off my business account but cannot attend to my simple request to move me back onto my original package, it is not my problem that Vodacom cannot hire people that can communicate properly with their customers.
