Dude. This sounds like a horrible, horrible situation. I gotta give you credit. I would have walked. I've seen a couple of your other posts and I know it's been said already but I'm going to bring it up again. Join P411!
Even though I've seen a few providers over the years I've only recently started to partake in this hobby regularly. I had the same issues you did getting started. Hardly anyone would give me a chance. Then I joined P411. It's like getting a prepaid credit card to build your credit score. They do some light, trusted screening then you can make appointment requests there. After 2-3 Oks from providers your credibility goes way up. AND most providers on P411 are pretty reliable and opposite what you described here. At the same time keep participating here and write reviews. Before you know it, you'll have no problems setting up appointments.
Don't get me wrong. We all deal with the occasional flake (and we all occasionally flake ourselves) but stick to well reviewed girls and you'll have a much better experience.
Good luck man and PM me if you have any specific question I might be able to help with having just been through the "newbie" phase recently and still not even close to a veteran.
