I encountered such problem before. How I deal with them? I get all his people and gang to come and meet me up. The gang have only three head. I paid each of them RM200 and told them and this will be the first and last time I'm paying you and settle. Till today, they no longer come and disturb me. Always remember to settle with them nicely. No point being rude with them. Just treat them as your friends and if you're kind enough, bring them out for a drink and chit-chat with them.
