I tried something similar lady but for me I just go no response
I have a possible fake booking this afternoon.
I e-mailed with my request to contact me prior to the visit ,he's done nothing .
Just sent a text to the number he provided so he can't claim he wasn't contacted .
I just put confirm booking please .it could be anyone but my number is now displated as I'm workimg today .
By 3 if no corresponding I will be leaving negative feedback, I will not contact him again.
I will get aw to remove any feedback he leaves me.
