Same situation here. Very thick SE Asian/Indian accent. He asked for Mrs Kevin, I said sorry wrong number. He said, no I have the right number and repeated my number to me. Said he was from a security company whose name is different from those mentioned here. I said sorry I'm not interested, he said yes ma'am you are interested, this is a promotion call. I said, no I'm not and hung up.
Just got the call, sounded strongly Asian to me, he asked for "Lauren", told him he had the wrong number, he said this is the right number, you are Lauren, I hung up.
We just received a similar call but with an extended number - our number showed an additional prefix to this number being 507...so the number that showed on our call display today, June 5th, 2013 at 5:26 p.m., appeared as 507-647-495-9156.
We ignored the call and surprisingly (hehe), no one left a message.
