Check on Escort Scotland. This is what I found:
..."another time waster. Made an appointment for 4.30 but she would call when ready, she then called at 4.45 i went to the door but she wouldn't buzz me in, after trying the door for 5 mins she said she had another booking at 5.00 ???? WTF, so i left.
10 minutes later she asked if id come back for a half hour appointment, obviously the 5 o clocker had not turned up. AVOID, there is better out there...."
I hope it helps
