We got conned by these people a few years back. They use a sales motivated team to call as many companies as thay can. They harass you constanly if you give the slightest opening. What we do now (and to any other cold callers) is say THE DIRECTOR/OWNER/PROPRIETOR DOES NOT TAKE INCOMING TELEPHONE CALLS ALL CORESSPONDENCE IS BY E MAIL ONLY, then give your work email, that way you can respondor junk as appropriate. I am convinced they are on commision, so if you ignore them, they just move on to harass someone else easier.
