Just got my email now, although it doesn't say if I'll be paying nothing, which it was when I first did it, or £22, which it was when I re-applied.
Presumably they've had to send these as they'd be on shaky ground and probably end up with credit card chargebacks etc if they'd just gone ahead and charged everyone the correct price, even though we'd all guessed it was just a cock-up but any new members post PSG or applying for the first time might have thought this is the norm.
Silver lining is it might knock the sorting of our shite website nearer the top of the agenda, if it isn't already there!
