Scammer dragged you into his turf and thrown dirt on you until you basically give up. You cannot communicate scammers into doing what you want. The solution is to auto-send all callers not in your address book into voicemail. The only solution to phone scams is some sort of government oversight and enforcement, possibily delegating part of responsibility to providers for allowing criminal behaviors to take place. Basically KYC for telecoms or charge people extra for making un-auth phone calls. This will make scams very expensive and turn them into losing business proposition.
