Good points in this thread. Agree with others; OP should get over it but also everyone, WGs and punters alike, need to have their own iron set of rules system for comms and confirmations to avoid surprises and keep schedules good.
She's definitely in demand - I had an MMF with her a while back (she's well up for DP and DVP) and mentioned how hard it was sometimes to get confirmation etc. She showed me the front of her phone and I shit you not there were like 300 plus text messages waiting to be read, said it was just that week

Recent GB discussed on here involved Lauren and unfortunately she did cancel on the day. However, having double-checked with a member or 2 off here she gave us all good notice and offered a bit of good will arrangement as well for the next one, similar to what the OP got - It's extremely rare from my perspective that a WG will consider losing money like that and I think it says positive things about her attitude to punters.
The reason she gave for cancelling was family related and I do believe her as she took her number down as well.
Thing is with Lauren that whilst the profile is new, she isn't (despite how fresh she looks) - this is her third stint in the UK in as many years between London (I remember her as a smoking hot Tamara Tease back in the day) and Manchester and her rep has followed her; Manchester Gangbang girl and all, so she's got a proven track record for being a champion cock artiste with comms and scheduling to match.
She also seems to have managed to keep in touch with, and maintain the loyalty of, a bunch of regulars who can afford like 4hr bookings with her as someone mentioned. That alone says positives - for punters to stay that dedicated she must be doing something right. So between her regulars and the rest of us trying to bang her she's got a lot of interest.
It's such a huge difference between her time as Tamara Tease (hardly reviewed over something like a year, bit of a hidden gem) to now - high profile with loads of reviews in 6 months.
The other thing is she's got a kid now which comes with its own set of responsiblities and dramas I imagine. I'm not saying it's a get out of jail for free card but it's a damn sight better excuse than most WGs come up with who're usually either fucked after a night out, can't be asked or get better offers.
Definitey think she had some challenges recently with comms as it took the GB a while to get sorted, again unlike her. Between family and the recent holiday as well as a lot of demand she seems a bit over-stretched. But judging on how she's responded with discounts and all I think she's well aware and hopefully will sort it. I think that'll be the true test of whether she's up there with some of true WG champions; whether she can manage the admin demands that come with a high profile and established reputation. Time will tell, let's see how the next few weeks pan out now that she's fully back from hols.
