I have seen Larettaxxx often without problems. However, I know that the hotel she had booked (and which shall remain nameless) cancelled her booking. I too had to rearrange, but that was fine.
She said she was 'nervous' about an outcall at your home; many WGs won't ever contemplate an outcall to a clients' home. Something must have spooked her.
I'm seeing her again soon. She's always been reliable with me; I guess it's unfortunate that your arrangements went awry.
