I went to visit Sabina.
Sabina, Dublin Female Independent Escort, profile on Escort Ireland
The door was opened by a different lady who said that Sabina was sick and that she (Sabina's friend) is answering her phone and seeing her clients. This has clearly been going on for a while as the lady who opened the door was the person with whom I had spoken two days earlier when making the appointment.
If this is true, it is a rotten way to treat clients but it may be a hijacked or faked profile.
