Well, that is not good. You see a provider after contacting through P411 , pay her rate , have a good time - you should get an OK. That is the rule at P411 - as far as I know.
Doesn't matter if it was a special rate , an incall etc etc . Well, OP, I would name the provider and report it to Gina of P411. I dont think she would take this too lightly and will fix it as soon as possible. Hope , this helps.
