Thought this was fun..... (not)

I've got the 30gb sky plan with Vodafone that was set to auto-double your data each month.

Today decided that i'm not using it nearly enough and would rather cancel it.

On their website you can choose the option to remove the 'double your data option' - but the button (which i suspect is just a submit) only has the option to 'Add a double your data block'

However upon clicking this it said ' you have now doubled your data '
what !

A quick phone call was then required and its all sorted but i suspect the page remains the same !
