Yeah big fail there 
I've seen Bethany before and while I enjoyed my time and had intended to book her again if she comes down my way again, her response on here has me re-evaluating whether I will.
I'm in the same boat, especially with what seems to be a significant price hike (although I don't know if that's just for Oxford/London/South East).
Has she quit yet?
On her profile, towards the bottom she has a list of dated updates. On 25th Aug she said Manchester (around Xmas) would be her last tour and she'd be quitting after that although she did say she may return. On 29th Aug she said because her friends want to escort with her she won't be quitting just yet. And as SeekingtheTruth says, she then goes on to explain how many people she tries to pack in during a day (very unusual and a dumb move although presumably at least honest).
I did notice the updates at the time and I'm pretty sure they said then what they say now but I'm not 100% certain (particularly with the update on the 29th as I think it was worded slightly differently but I could be wrong).
Perhaps, as Placebo88 has suggested, this is all the work of her thick pimp (husband) although even if the replies on here were him, it's still poor form and dishonest for her to allow him to pass himself off as her.
If she is genuinely quitting because of this one bad review on here, then she's an idiot. She should focus on providing a top service all the time, stop being so sensitive and keep her prices as they were (as that will probably have even more of a negative impact on her future client numbers/income than this review).
