Upgrade FAIL! Vodacom doesnt want our money.

I have been trying to upgrade for a week now with no luck. I went in store and was advised that because of the migration of the system, they were unable to assist me. I then attempted to do it online, this was also unsuccessful. I think phoned in to upgrade, on Friday. I was advised that everything had been processed and that I would receive notification via email and sms. No notification came through. I phone on Saturday and they confirmed that the order had been placed. I was assured that I would receive notification, I did not receive a notification. I contacted the call centre again they said that there was no upgrade request and they I should contact the upgrades department. I have calling for the past 1 and half hours and NO ONE is able to assist me. this is unacceptable. I require feedback ASAP! I have requested a specific phone on a specific contract, I better receive that phone as I have done all that is necessary to get the upgrade!
