Just a bit of useful punter knowledge on a subject that comes up time and time again.
If a WG, for example, promises anal, takes your money and then refuses to provide anal, she has committed a criminal offence. The offence is fraud by misrepresentation (also known colloquially as 'clipping') under section 2 of the Fraud Act 2006 (see below):
It doesn't matter that contracts for sexual services are unenforceable (that is a civil law matter) as that is distinct from the criminal offence of fraud by misrepresentation.
I appreciate that in reality most punters wouldn't demand their money back with a threat to go to the police, but it is worth knowing about the criminal law position on this so you can bring it up in the subsequent negotiations about the return of your money if necessary.
As a matter of evidence, where possible get the WG to confirm services (a yes or no in answer to your text) by text where possible. I'm aware that many won't do this, but some do.
This will never be enforced with regards to sexual acts.
I know of a case where a escort went to a punter at his home address they got in to an argument over him saying he has not had everything he has paid for a certain sexual act she did not provide he demanded the money back she would not give it he snatched half of it back from her bag there was a bit of a struggle she ended up phoning the police.
2 uniformed police officers turned up she told them she was an escort and told them what had happened about him snatching money back over a certain sex act she did not provide, they told him she had done nothing wrong and he was bordering on getting arrested for not only man handling her with the money but trying to keep her there.
The police officer said it would be best if he returned the agreed money to her and they both move on from it or take a trip to the police station and asked the girl if she wanted to press charges against him snatching her back and grabbing her arm. She decided not to, the police told the girl that usually over money agreements this is usually a civil matter but this case was a punter trying to force something sexual on her that she did not want to do so she has a right to say not to a certain act. They said to her they could have arrested him and had him up on a few charges but both parties wanted to leave it.
I know of this because my sons friend was in the police and he told us about some of the stupid things he has got called out on.
Also I am sure I remember something being in the paper once about a punter calling the police on an escort to his house where there was a dispute police got called and punter got turned on by police. Its not illegal for any punter to pay for sex but there is situations where the punter can get arrested.
So I would be careful on thinking calling the police is a brilliant idea unless an escort is trying to blackmail a punter then that type of thing would be taken serious by the police and it does as some girls have been done and prosecuted for blackmailing punters.
