Same thing happened to me. A supposed solicitor Barr Albert Nieto Esq. contacted me by regular mail from the company "Integrated solicitors". Phone number: +34 911 019 619. Email: barralbertnieto@europe.com. Adress: Ciutad di Barcelona 09, Madrid 28007 Spain was marked on the letter.

Over the net there is a firm with different attorneys supposedly located at: Ciudad Barcelona 9
28009 Madrid, Spain.
Please note the postal code difference!
The phone on the letter was the same as the one on the web site but the fax number was different.
