This number called my office today asking for our CEO by name. The guy had a very thick Indian accent and said his name was Tim Johnson and he was calling on behalf of Heather Brown. I put him on hold to check the number (I do this with most numbers since the calls that usually come through me are sales calls and I screen them out). He was on hold for about 15 seconds, then hung up.
A woman asked for one of our managers, claiming to be phoning on behalf of her boss. I asked what in reference to, but she had no idea, only that she was to connect our manager with her supervisor. When I said that we don't transfer calls without knowing the purpose, she said (in a rather gosh-golly-geewhiz manner), "Oh well, I don't know, I'll have to find out and get back to you. Thank you, darlin,'" and hung up. As I've noted on threads for other annoyance calls of this type, she won't return.
