Calling to invite to their seminar.  The caller states that I should've received an email by now, which I have not.  Refuses to provide further information unless I register.  Well, isn't that contradictory?  If they already sent the info to me, why is he refusing information unless I register?  When I informed the caller that I will decide to register once I receive the information.  He thanked me, and said to have a good evening.
