Trying to upgrade my cellphone contract.

I have been wanting to get an upgrade on my phone contract from Vodacom for the past 7 days. I went last week Friday to the nearest Vodacom shop where I stay to be told the phone I want they out of stock. So went to the next Vodacom shop to be told they are offline. I filled in all the paperwork and they said they will contact me as soon as they back online. I am still waiting. I went back to the store three times during the weekend to be told they still offline. So I decided to do the upgrade online with the my vodacom site. Got a message said they are processing it. Monday came no one phoned for confirmation. Tuesday I phoned they sent another email to the department for confirmation. Heard nothing. Thursday came I phoned again. Was told they still processing it and I will get a confirmation. Still waiting. Phoned yesterday to be told they still processing. REALLY! I was told to get an upgrade on my phone would take 24 hours for confirmation. Its over 8 days and I am still waiting for confirmation. What is going on?
