Booked her once but no reply on the day. Haven't bothered to try again yet.
Not sure why you've decided to swerve as the only replies were clarifying who she was. Found GB's BB listing and it's the same lady, but had a quick look and it seems to be one that just sends you to AW. And to the best of my knowledge she has never offered BB there. Site also lists lots of other SP's who don't offer BB.
Not a member on that site so it's always possible that they are listed as providers that offer BB on the side.
