Being over charged for pictures

Has anyone else ever sent a pic to one of the Sexstation channels and been over charged. Last two times I have sent a pic I have been sent 3 £1.50 texts in return.

I sent a picture in the other day which is supposed to cost 3 pounds and they charged me 7 its a fucking piss take.

From reading around a few different sites they seem to have a bit of history for ripping people off with DVD scams and so forth. I won't be using them again.
