A female called our company today enquiring as to our printing/mail-house situation- refused to introduce herself or where she was calling from. Denied that the the purpose of the call was sales-related, instead demanding to speak with the contact that her company has obviously purchased from some data-supply group. When asked what the call was regarding she became quite aggressive, yelling "THANK YOU NO I'LL CALL ON WEDNESDAY THANK YOU I SAID THANK YOU GOODBYE". Very odd, very rude?
