She may be in the process of changing area's so thought she would take the opportunity of ripping off some of her regulars as well, might not be just you. I have seen a few profiles on AW with good feedback - gained from incalls but rip off everyone that they do outcalls on - the usual "just got to pay my driver etc.," routine. On a second meeting, you of course contact her direct and don't use the booking system so can't leave her bad feedback - if the profile was still there. Then there is the other issue with outcalls - she knows where you live, so how much fuss do you want to create? If she is prepared to rip people off then what else could she be capable of doing. In practise, they like to stay below the radar and not draw further attention to themselves but, there is always the odd crazy one that could cause issues.
Maybe her profile will reappear in the future in a totally different area of the country? I reckon with that amount of feedback, she will try to keep it. There may be a chance to drop some neg feedback later on if you keep an eye out.
Just put it down to experience and learn from it then move on! Not being hard nosed about it, but if you are going through the "can't sleep, stomach churning issue" days later, then you aren't really cut out for this game! The golden rule (unfortunately) is trust no-one. Doesn't matter how many meetings you have, how friendly they appear to be, do not trust them. Confidence tricksters work in exactly the same way!
