Received a call from automated system at 10:30 am. The recording stated that if I was (my full name) I should hit numeral 1, I did, I was put on hold for a moment or two, and then a man answered. He gave his name, and quickly spewed out something and asked how he could help me. I said, "You people called me, I'm waiting to hear what you want." He disconnected without a word. This was not the first call received from this number, just the first time a human came on after being placed on hold, usually I get tired of waiting and hang up.
My experience was the same as LIssa's. Only when I asked who it was he said "we have an important business matter with (my full name). Can you verify your date of birth" I said no and hung up. I am NOT going to give out my DOB without knowing who the company is and I advise that no one else does either.
