If we dont get a text by tomorrow then i think it means they wont be making any changes which after the backlash wouldn't supprise me at all.
But if they are going to make any changes they will send us text's, so simply put, no text=cant cancel, unless they do charge us after 1st of june at which point we will be able to cancel on the grounds that no notice was given. At the end of the day their b*stards but their not stupid if they make changes they will give notice.
