Just get a new SIM card and call again.
Same situation here and want to see one of their new girls .. might try doing this.
Update: failed, phone carrier matters. I got a 7-11 Speakout SIM which was probably a dumb move because it's not a very reputable carrier and I'm not sure if the handler can see that it's Speakout instead of Rogers (the tenant carrier that lends out bandwidth). Probably should have gotten a Public Mobile instead as that is more prominent. I've also tried an Android app called TextPlus (gives you a 604/778/250 area code virtual number) but got a rejection as well after making an appointment but then getting cancelled later (I lied and said I was with Fido...).
So basically if you call and get right to the point about booking girl X, she will ask:
1) what's your race
2) is it your first time
3) what is your phone carrier
I think if any of the answers sound fishy, handler will make up some excuse to defer rejecting you on the spot (Chinese or maybe most East Asians don't like to say No to people directly....). In my case the rejections I've gotten before were:
1) sorry she doesn't want to see new customers (err... OK? But you're on Leolist as well...)
2) sorry she doesn't feel well (right, easiest excuse ever... and then you stop replying me even when I ask to see another girl)
It's a bit ludicrous that daynight has become this exclusive club that somehow WON'T TAKE MONEY FROM WILLING CUSTOMERS. But it makes sense because they have not compromised their integrity with fake pics and renamed girls much, where as legendfantasyland has gone to total shit. maybe they've already established themselves enough with Chinese pooners to not have to bother with any risk.
In case you're wondering why I've gone to such lengths - I find one of their girls really enticing but have my number banned way back from pulling a no show.
