Upgrade Disaster!!

So on Friday I called to cancel my contract. The gentleman I spoke to was very helpful and gave me a good deal. He also said that I would get my phone today (Monday) which is apparently not the case. The confirmations team called me... to now only confirm my order. I was frustrated but went through the process. When the lady confirmed my deal she said that the deal is 500mb a month but I was promised 5.5Gigs a month. Now this really annoyed me, and so I asked her to put me through to Retentions again as I am not interested in the upgrade or being a client with Vodacom anymore. Got through to Retentions they sent me the cancellation form and the amount i have to pay to cancel my contract. I then payed and phoned back - another retentions person that i spoke to says it takes 72 hours to process it, and then assisted me. He was very patient and calm even though my blood was boiling. We spoke and I agreed to stay with vodacom, he confirmed that even though i sent through a cancellation and made the payment it would not affect anything on my contract. He then said he would make sure that he will go to the confirmations department himself to tell them to call me now to confirm my upgrade. And to no suprise,,,, here I am still waiting for a phone call.... I have been a customer now for 17 years... and I am truelly disgusted with the service I am receiving right now. This means I will have to call AGAIN... and then wait for someone to answer the call after a HOUR AGAIN!!!! Come on Vodacom....what am i supposed to do to get some decent service!!!???
