Incorrect upgrade put through

About 2 months ago we did an upgrade on our data contract and when my husband was on the phone with Vodacom the consultant asked him about upgrading the number he was calling from. That number is on my account/name and my husband advised the person to speak to me. I had told the consultant we do not want to "upgrade" to a data/airtime only package, as we were waiting to upgrade to a new handset when we found something that we could afford. I have called Vodacom back, the query apparently had to be sent to cancellations to be looked at. I have tried a few times to get this sorted, but again I hit a dead end. We are now tied to another 24 month contract, and no handset, and we said we did not want this to happen. When the consultant had called me, I was unaware of what he had spoken to my husband about, so I said to the consultant my husband can go ahead and do an upgrade, but he needs to first hear what it is he wants. He kept on about us reducing our monthly costs because we were in essence still paying off a handset which was already paid for, but the contract was rolling over month to month. I told the consultant we want a handset and not to be tied to a data only contract. Now we can't get through to anyone, our queries keep being escalated and we get told some one will call us back and it has never happened. I want this contract cancelled, if this is the service I must get then I'd rather not deal with Vodacom. I have a few numbers on my Vodacom account, the number I'm referring to starts with 082769****
