Seeking help via GreenAddress support email address info@greenaddress.it resulted in a detailed answer about recovery of the bitcoins and forthcoming costs. I agreed to the costs and send all the information
Are you sure you contacted the authentic greenaddress staff? I'm pretty sure that they don't charge to provide instructions on how you could potentially recover your account. Or perhaps I'm interpreting your words incorrectly.
We don't charge for instructions, you're right;
However in this [case](
https://www.reddit.com/r/Bitcoin/comments/4b5gma/looking_for_help_or_contacts_who_know_people_at/) his request required some ad-hoc coding and ad-hoc security procedure to help him out so we asked for him to cover those costs.
baudoin, as soon as we have time to develop either an ad-hoc solution or something generic we will send you an update
