Vodacom Online Upgrade

I did a upgrade with Vodacom online. This was by far the worst service I have ever received from Vodacom. The upgrade was done on the 22 Aug. I still haven't received my upgrade almost 4 weeks later.

First they didn't have stock. Nobody even informed me of this. When they finally got stock the shipping address they provided to Ram couriers was incorrect. Even though this was not the address I provided for shipping. I changed it numerous times and still it was not corrected at Ram couriers. Finally the parcel was returned to Vodacom. Again I was not informed. When I phoned again I was told to do the whole upgrade process again.
