Wow, sounds like you were seeing a "managed" provider to put it nicely. What you describe is B/S/ The bait hot pics, the switch not the girl in the pics.
Try joining P411 and then you can shop on there, looking for newbie friendly providers. Also check out the TER Los Angeles or Orange County ad board. Plenty of great escorts advertising there.
Just make sure you see well reviewed escorts and you shouldn't have to experience a b/s again.
Sorry that it happened to you dude, but you weren't robbed (no gun, knife, etc), you just made a bad choice! A simple search of the phone number and photos shows ads all over the country (CA, AZ, IL, FL to name a few) which is a lot for even the most traveled providers. And the kicker... absolutely NO reviews! And, you said that she was not the girl in the photos?? You should have left right then, before any money changed hands!
It is not about being unlucky. Actually, you may be lucky that this was the worst that happened, as there could have been more than financial loss. Think with your BIG head, do thorough research, and ONLY see well reviewed ladies! As has been mentioned previously, invest in VIP, read the details of the lady's reviews and you will better understand what to expect going in.
I really don't mean to be harsh, but guys need to approach this with eyes open, not just a wish. There are many, many quality ladies on TER and other sites to choose from. But regardless of where you find them, you have to make educated choices. The best you can do is consider this an expensive lesson, write a review of this lady to warn others (you can since you had something of a session), then put it behind you. The good news is that it can only get better
