Thats interesting, I've been posting on CL for a few months now, in all that time I've never had problems with no-shows. Now all of the sudden in this past week, I've been getting more no-shows than actual clients. Someone's definitely messing around, and its really damaging my business.
You will find this happens when you get a little more popluar. For some reason, there are some SP's in the area that feel they should have more bookings than they do and instead of looking inward to see why they are failing to meet their own quota, they feel that it is something that some of the more popluar SP's are doing. Their logic, if they can stop you from getting bookings by filling your time-table, then those who can't see you, will book them.
Don't ask me to explain the logic in that, but that is what they do. We have had it happen to us many times, especailly when we hire new girls.
Next is that your CL ads will get flagged so much that CL will freeze your account, forcing you to create another with a new email address and phone number. Lot more difficult for an INDY to get around that than an agency. It really sucks the games that people pay.
My suggestion is to have yourself a cancelation list. That way when someone pulls a no-show, you have a client who you can call back and is eagerly waiting to see you.
Good luck
