Contract upgrade horror!!

This 1-star rating needs to be reviewed because Vodacom doesn't even deserve that 1 star.

I am really upset with Vodacom. On 28 March I called to check on the status of my contract, only to be told it is expiring at the end of April. I, then, inquired about upgrade options, on condition that I still get my discounted any network minutes and data only. The consultant clearly understood what I asked for and told me she could only do the upgrade for me and will put me through to retentions to get the discounted minutes, since (according to her) they were the only ones who could give me the minutes at the current contract's percentage. She put me through and I was told they cannot add the minutes because that is a stand-alone date contract. They then said they are escalating the matter for the contract to be cancelled and then start a new one that is bundled with minutes. I tell you, from the 28th, the contract is still not cancelled. That same day, I called a few times to do the cancellation, but still... not cancelled. Every time I call, the answering consultant tells me he/she is escalating but, to this day, that is not done. I am really tired of this back and forth, I just want Vodacom to just cancel this contract. I am not sure I even want to explore other deals with Vodacom. I have had it!
