They call several times a day and from the Yellow Book Yellow pages online. I have asked them to stop calling and they still call. We are on the national do not call list and I have reported to them. I called back about 1 min later and the phone number has been disconnected, they are somehow using phone numbers that have been disconnected or no longer in service, how is this possible.

Have received 2 calls this week from this number.  The callers, with strong Middle-east accents, say they're updating our yellow pages business directory information.  We just renewed our advertising w/AT&T yellow pages so this is a sales scam. Same thing happened multiple times last year although requested they not call back but they keep calling.  Filing a report w/DO NOT CALL doesn't seem to do any good.
