oh yes. i just ask these people to send their representative over to my office. when he's here, i ask security to take his keys and cell fone as "security measure" and make him sit for a few hours. then i call him in and we all sit and grill him and ask him to speak with hyis boss and so on ... another neat way is to ask these guys to come over and meet you at a fictitious address. he'll go, not find the place and call you. you then say that you are on your way and will reach in 30 mins and ask him to wait. it works! i've never been bothered by the same people again!
