Error logging in

When I try to log in to my ID Residenza Santa Cecilia the answer is that "it is impossible to log in with this details" link: (https://www.openstreetmap.org/login?referer=) If I try to recover my password by sendin me an email at info@residencesantacecilia.it with a new one the answer is that "it is impossible to find my email address". Because of this I suppose that my account has been cancelled so I try to create a new one (with my email address info@residencesantacecilia.it and my name Residenza Santa Cecilia), but the answer is that the email and the name already exist.

What can I do to log in my OSM page? Can you help me?
