Trying to find permaculture design company Porto Portugal

Hi everyone, i am trying to find a company or rather a person because i lost their contact info. All i remember is his name was Antonio and he had a permaculture design company and was based in Porto. Thought maybe he might be on here.
Earlier this year i had somone at the property who put an ad on a facebook group to sell an old hymer for parts. Antonio put a deposit and has not contacted me since. I have tried contacting the person who posted the ad originally but no luck.

Since i dont use facebook i cannot get on this particular forum, "hymerclassics"i even tried signing up to facebook but my id was rejected, cant believe i even tried but after a few frustrating hours i gave up and came here.
I really want to get in touch with Antonio so he can pick up his parts,
hopefully someone knows him here
Thanks

Larry, in reality it is  Antonis issue unless its a hinderance.. Facebook is not hard, maybe you were trying to have name someone else  is using.
