she also said i had shown disrespect to the girls emily and heidi which was news to me as i have never had a cross word with either girl when i asked for examples she refused to answer.so there you have it a comedy of errors resulting in being barred.
From what you have said it suggests the agency owner thinks you have done it previously to Heidi too.
If you change sim card and give a different name you will be allowed to book. As on mobile phones people do sound quite similar and no agency is going to say when you say
"Hi its Mark can I book soandso tonight"
"wait, aren't you Alenski, didn't I tell you that your barred"
For simple reason as there is always a good chance they are just jumping to conclusions and wouldn't want to risk it. So unless you make it obvious, you will be able to book.
