No BIS for almost two weeks!

On 20 September my BIS expired, but I had already bought and loaded a new one. That night (20 September) my internet connection stopped altogether, meaning I had no emails, apps or BBMs. The next week I took the phone to two different Vodacom outlets here in Pretoria, and they told me the problem was on their side, with them being unable to activate some BIS bundles. I also phoned the help centre on numerous occasions, and was given the same story - and also told the engineers were 'working' on the problem. Well, it is now almost two weeks later and my phone is still unable to connect to the internet - this is really not acceptable. I use my phone for both personal and work purposes, and because of this I have missed a couple of really important business emails, amongst other things. When is this going to be fixed - I need a functional phone, that is what I pay Vodacom for!!!
