I had something similar to that happening to me one time, can't remember wich agency it was(but not candy shop/chloes), when they change booker, it seem the guy had writen the wrong NAME and Hotel room. I mean missing one ok, missing the 2... cmon. And it was not even a similar name, i gave them my real first name, but for the forum we will say mike, and they writed something like sebastien i think if i remember corectly. I dunno but would it had been Matt instead of Mike for exemple... understandable, but it was not even close, plus the guy had the wrong room... and i ALWAYS make sure to have them resay it.
I guess they mixed up files or something. The poor girl even asked reception, but since she had the wrong name... no luck.
But to come back on what you say, guess mistake can happen, at least the girl did show up finally, from what you are saying she could had call this a night off being pissed like she was... As for the chat... happen to me sometimes but remember one thing, its your business to watch this, not hers. If you think this is taking too much time, ask her politely to start action. Personally its rare i have time for 2 services, i talk too much, and everytime i tell myself at the end "next time buddy, make it short"
To get back on topic, i may not be the best judge, hobbying only once every couple months, but so far i didn't had problem with Billy, when he was at Angel he actually help me a lot one time, and my last SP was from candy and everything got smooth. The only time something happened was when a girl(that isn't there anymore) refused to come to my hotel, it was the second time it happened to me tough, and the other time was a different girl/agency. This is when i stoped to use the hotel Elysee, too bad cause it was perfect on everything, room/price/location.
The girl said it was a crack head place or something like that... just because there is tons of hotel there stuck together and look cheap, and there all 2 stars pretty much i guess. I used that place 3 times total and everything got smooth, its run by chinese and there very friendly. I guess no SP would refuse an hotel on sherbrooke tought, even if in the end, this is pretty much the same type of rooms. Just because its on sherbrooke and not on st-hubert... not a big deal, just have to walk a little more, but last time i was coming back from a 1 month trip and believe me, with all the stock i had, damn i founded the walk long from the bus station.
Anyway...lol i am a little bit off topic here, but one thing is sure, Candy/chloe's is a good agency, if they can finally decide to merge all in one name/agency, that will be perfect.
