A prossie could decide to not want to see you for any reason. It's just part and parcel of punting. There's many times I've tried to contact various prossies and got nowhere with them. It's just the way it is. Yes, it can be annoying and frustrating, and minimum feedback restriction rules are bullshit in my opinion, but, it's never worth fixating on just seeing one particularly working girl. Such a way of being will just get you no where. If you've never actually met the prossie, you do not even know for certain that you will even enjoy her company. In fact, I take the view if the prossie isn't interested in my attempts to contact her, then she probably doesn't have any particularly strong interest in my custom or in giving me good service. At that point I stop thinking about that prossie and move on to a different one.
I'm sure you'll get over it OP, plenty more prossies in the big wide sea of punting to get fixated on.
