Vodacom Upgrade Disaster

Good day, My previous complaints refers. I app**** for an upgrade but the specific handset was not in stock. Hence I cancelled the upgrade last week Thursday only to find out that the same phone is in stock but just with different memory capacity. Not once was I made aware of this by anyone from Vodacom. I went ahead and upgraded again on Friday 12th. This morning my April Vodacom "bill so far" shows My "old" line rental for Smart L of R660-00 plus my "new" upgraded rental on Smart 4gb of R494-78. Also it shows my old handset fee of R50 as well as new handset fee of R391-30. I do not even have a new handset in my possession as yet. Not only that, I have also been charged the handset fee of the handset which is out of stock, the exact upgrade deal I cancelled and not the new upgrade I requested on Friday. This issue is now getting out of hand and heading for a disaster......Is there any person at Vodacom capable and willing to assist and sort out this mess. Even Telkom is now in my view better at service....and in all honesty they are the worst I ever dealt with.
