CellC Data Bundles "Out of stock"?

So I've got ADSL at home, and thus have no need for CellC's very cool new 24 month data special.

However, I'm going away this month, so I thought, let's get a CellC SIM card, and buy a 1Gig data bundle and use that.
One would think this would be fairly easy.
Not so.

I went to the CellC store at Cavendish and was told that they would be unable to sell me a data bundle since they are, and I quote: "out of stock of the virtual bundles".
Now, I may be missing something big here, but how can you be out of stock of something "virtual"?

I now have to wait for them to be "in stock" or - and this is more likely - go somewhere else.

Could someone from CellC clarify what the store means by this as I am thoroughly confused...

I PM-ed CellC with the same message as above, but unfortunately s/he completely misunderstood my problem and proceeded to tell me that there are plenty of speed sticks at the Cavendish store.

What I want is not a speed stick, but a simple prepaid sim card and a 1gig data bundle.
Apparently I can't get that since they are out of stock of data bundles.

I still don't understand how you can be out of stock of a virtual item...

The mind boggles ...

Just buy a prepaid sim card. Recharge with R250 airtime and convert that airtime to the 1.2GB data bundle. This can be done by dialing *101*4*250# . (For other bundles: *101*4*price of data bundle#)

Why they don't explain this anywhere on their site (or at least not anywhere I could see it) is beyond me!
