I get these calls too. It sounds like an underground prostitution/drug ring? Some oriental woman kept asking me if I wanted to be her boyfriend and then marry her. Like she was trying to get into this country.
called for me to attend Marriot presentation. When supervisor called back the ansering machine was recording, and she said she would call back...she did. 4 times within 10 minutes, and at the 3rd ring (answering machine is set to 4) they would hang up. Suppose they do not want to be recorded "FOR SECURITY PURPOSES"! lol....
they started calling mu husband cell# and he evidently did not understand them so he had them call me... (thanks) I am sure they got his cell # from an ad on craigslist we had placed. Some oriental woman kept yaking at me and then put another one on the phone and then another..... never understood any of them.
