One of the people on it is also a YourEscortSite client, but I notice that the site's American and unsurprisingly paranoid about being associated with prostitution.

You could try pointing out that prostitution is legal in the UK and being a silly thing, you didn't realise that there was any issue with it in the US - the T&C don't say 'no sex', they just say 'nothing illegal'.

If that doesn't work, I suspect that forgetting the $30 will be the sensible option, but console yourself that this will probably end high up on Google when people search for their name and cost them more than that.

Did you pay by debit or credit card? If so just do a chargeback.

Update: I received a friendly reply from Slixa that I can re-open my account and that the purchase was refunded once they deleted the account.
All good between me and Slixa now 
I shall re-open the account and hope that they will work for dem dollars and I'll get some bookings from there.

Does anyone get any work from there at all?

I had no jobs from slixa. I was advertising there for 2 moths and zero book or emails

What is it x

Yet another directory.

Thank you Suziblue!

Hmm..., it feels a bit like Eros. Not much happening on the UK front.

Eros was good 4-5 years ago. I had many dinner dates booking and a lot out calls to expensive hotels but now is crap.
