This isn't the worst problem as it only cost me 25p ... however, when you have a Travel Pass and you're abroad you're advised to text 'status' to 23456 to check how much data you have left. I did this several times when on holiday as I didn't want to go over my allowance, not trusting Virgin to tell me. In fact they did tell me, but not before my texts just to make sure.
However, I'm not at all happy at being charged by Virgin to text Virgin to check something I bought from Virgin. It's just wrong, somehow, and hopefully something that will be fixed.
