Where has my Contract data gone

I have a 5GB data contract with Vodacom and on Saturday 1st august I should have received my months allocation. The system was down for 24hrs and only working on the second of the month, on the third of the month I checked how much I had used and was dismayed to find 4gb had been used. So in one day for e mail and internet browsing I had used that amount of data. I phoned customer service on Monday afternoon and was told they would look into it and I would receive an SMS confirmation.....Still waiting! <br> Also I would receive a phone call within 24hrs to let me know what the problem was....still waiting!<br> <br> I went to the Greenstone outlet next to Mugg and Bean today and a consultant asked that I check my windows updates, this I have done and its definitely not that. Thanks Vodacom for your normal **** service, You are quick enough to take the customers money but don't deliver on the goods.
