3 calls to new unlisted cell number in April 2012. No messages. Either Verizon is sharing new numbers with it's "partners" (shocking. SHOCKING!) or the call is for the previous owner of the number. Black-holed the number.
Sounds like it's a person -- starts off with female saying "hello, oh, hello (giggle) I was just having problem with my husband. I am calling you because you have previously stayed at one of our resorts and have qualified"
I don't know what was said after that because I hung up and blocked the number. I say it sounds like a person, but was definitely one of the computer-generated voice response calls.
