JUST LEAVE... and feel free to waste there time and please do not pay them, they cannot do anything... at all. They literally have no legal powers whatsoever. Everything they say is made up and so are all the five star reviews. They'll make empty threats but u can ignore them, some are quite funny. They'll send u letters but nothing will come of it. They can't do a single thing unless they take u to court, which they won't because they're contact is a weak as they are. There are many useful websites that also have zero respect for them, which will also tell u how to leave and FB and Twitter pages etc that hate there guts... definitely worth checking out. Eventually they'll go under, sooner rather than later!
