This could happen....
I must add that this is not me, but this happened to me. I had to wear a leopardskin bikini all day. Out in the bars, shopping, at the water park, everywhere....
I received a letter from them about something else, probably marketing bumph about the new season or something and tagged at the end of that was the information that the subs were going up to £12.99.
So you probably did get informed but didn;t read it.
