Upgrade Requested - Call Centre Not Available!

I have been trying to get a hold of Vodacom to finalize my upgrade request. I have tried ***4 as well as 082111, I can't get through anywhere due to the call centre being unavailable. No one has contacted me as stated in the e-mail.<br> <br> I am considering a contract elsewhere due to utterly bad service. It is not supposed to be so hard to arrange an upgrade.
