Angry customer service voices with accents asking for personal information claiming to be the yellow pages

At work, I keep getting these calls from a guy, (with a very thick accent that I can barely understand) from "Yellow Pages" trying to update my business listing. Then when he confirms the info he wants to transfer me to "another department" so that they can confirm the info as well. I just hang up at that point. Then he calls back disgruntled, and I tell him he has to hold for the business owner, and he hangs up. We just updated our business listing a month ago, so i know it is not Yellow Pages.

I had the same thing happen with a similar call updating info for a discount, but from Verizon. I was told to say YES to everything, including "Do you confirm changing your plan from blah to blah?" I confronted them. And when I told them that my boss' husband was a big time lawyer, and I did want to get into trouble for updating info that I wasn't supposed to, they quickly said good-bye and hung up.

I have received call after call, at work, from people claiming to be the yellow pages updating our business info. They have all of it already and I just confirm it but then they try to get me to answer yes to a bunch of computerized questions. I usually just hang up at this point. One time they called and I hung up I did receivean angry call back but most times that ends it for a month or so. The last time they called I asked if there was a number that I could call them back at and I would be happy to verify anything at that point and they hung up on me.
They called again today and I hung up on them and then tried to call the number back and got "Can not complete call as dialed" message...pretty sketchy!

Calls every #^*@/ day!
