Gross Incompetence AGAIN

I have had a red VIP contract with Vodacom for a number of years. I called to port my number a month ago as I needed more data on my contract and there were better offers than what I was on, for a lower price. I was convinced to stay with Vodacom and promised a cheaper cost on my package plus additional free data - active from 1 September. This morning I checked my Vodacom app and not only am I still on my old package and data, but the amount I am being charged is more than my bill should be. I am now (as I was miraculously last month suddenly as well) being charged for a contract including a device, when I have always been on a sim only package. I then spent 32 minutes on the phone trying to resolve this, spoke to three different departments, explained the above story three times, only to be told that they could see that the migration was supposed to happen but it was cancelled (this despite me calling a week ago to confirm that everything was still inorder!).... I then got cut-off before anything was resolved. Another 'amazing' experience with Vodacom! I should have just ported my number.
