The person who called me claims that they can send me money that I had invested in an online trading platform that was found to be fraudulent and was subsequently shutdown. This person claims that my funds will be sent without me making a payment to them until after I have received my funds.
Did you invest in any online trading platform if you did not then just ignore them they are fishing for a potential victims, but if you did then there's a possible leak of data.
Bitcoin.org is not a regulatory website, it's an information website, there's nothing on their website that says they have control over any trading platform, obviously, they have an attempt to scam you, don't be greedy to fall to their scheme, you're wiser than this.
