how many times does this number have to call and receive no answer before they will wake up and stop calling.  No one wants to be bothered by them.

They called and did not leave a message.

Called looking for a Judith something or other.
Claimed to be located in Phoenix, Arizona;
4727 East Bell Rd.
callback number of 480-263-9725.

"Manager" David Webber claimed they are not required to abide by federal telecommunications laws by not maintaining a no-call list by phone number and do not thing the Federal no-call list applies to them. Also said that they are only required to maintain a no-call list by _name_ according to Arizona law.
The "Manager" also stated that it was my responsibility to find out how they got my phone number, not theirs. That it was submitted on their web site and they don't track IP addresses, but then claimed that it was submitted from a public library IP address. Which is it? Do they or do they not record IP address if information is submitted on their web site??? (sarcasm)
Other than that, I have no idea what they were trying to sell. I'm surprised they stayed on the line as long as they did.

We had a call about 3 hours ago from this number.  Stopped ringing after about the third ring.  No idea what the number is.

We had a call a few minutes ago from this number.  Stopped ringing after about the third ring again.  Irritating jerk, calls even on a holiday!
