They hung up the first time I answered then called back wanted to speak with whoever was in charge of purchasing products for our manufacturing machines I asked him what products, he said he was not selling anything just wanted to ask some questions I told him we don't participate  in over the phone research and he said because it's against company policy and I said yes it is.  Then I kicked myself as I never answer anyone's questions with a "yes" because they may be recording me and used that against me to their advantage.  I think they're wising up so they are rephrasing their questions to elicit a yes response.
