...but if one person can learn from my mistakes then my embarrassment is not completely wasted.
I booked an appointment with 2 providers on Monday. The website I went through required one week's notice and a deposit. That should probably have been my first red flag. I traded e-mails and spoke on the phone and everything seemed to be going ok. Well, today is the day, it's less than 1 hour for the appointment and I haven't heard anything back re: the precise location. 
The last I heard was a mail on Tuesday saying that the address was forthcoming. Since then I have sent many more e-mails and left a few voicemails too. Nothing back. Maybe I will get a call in the next, hmmm, 42 minutes but I don't think so. So I've been ripped off in the extreme and there is nothing I can do about it...other than lick my wounds and take better care next time.

is the place I used, anybody heard of them before? I didn't find anything negative about them (I did a little due diligence, just not enough!)
I know that I have been extremely stupid but I thought I was above being duped. Lesson learned the hard way I guess. I was sure that if there was anything bad about this agency or website that I would have seen something somewhere but nada.
Bumming big time.
Oh yeah, if I DO hear something back in the next 37mins it is now, I will come back and edit this post. But I am thinking that ship has sailed...
You really need to do your homework. A reputable service will never make you pay a deposit. first mistake.
When a service has 15+ girls on their site that all look like top models and none of them have any reviews, that is a big clue it is a scam!
You just don't look for bad things, you have to also lokk to see if they have any reputation at all. I never heard of them till your post.
I am sorry this happened to you but you probably saved a few hobbiests in the process.
