.org and .es domains info. Cancelling .org domain in 1and1

Some time ago I bought two domains, .es and .org and I associated them to a Google Site.
In the beginnig the price was just 5€ each one, but after several years I realized I am not using at all .org domain, and, more important, .org domain "exposes" to all people personal data (email, phone number, even postal address!!...)

Example for my .org domain (... replace personal data!)

With .es domain this info is not so detailed, because it appears 1and1.

So I decedid to cancel .org domain.

I didn't see any option about cancel in control panel, https://clientes.1and1.es/
Googling, I finally found this
http://www.joomlaempresa.es/es/tutoriales/trucos-para-webmaster/125-como-dar-de-baja-un-dominio-en-1and1.html

Login in https://contrato.1and1.es/ I was able to cancell .org keeping .es domain at the same time. I fixed the ending date as the date where end my contract for that domain: meanwhile I am going to redirect  .org domain redirecting to a page where I inform that I am no longer using .org domain (right now I was redirecting both to the same Google site)
