Tried to talk to these people, but they are so rude that I wouldn't pay them a cent whether I had the money or not. I'm going to block them.

Another wasted phone call from these jerks. No message on my answering machine so I jsut file the complaint and delete as always.

Just go to your telephone company web site and BLOCK the offending number, so it will not be able to come thru.
But that's nothing permanent, because those Caller ID spoofers use a number for one day or so, then start to use some other number. The numbers they use are abandoned numbers, not yet reassigned by the telephone companies.
From Wikipedia:

Caller ID spoofing is the practice of causing the telephone network to display a number on the recipient's Caller ID display which is not that of the actual originating station. The term is commonly used to describe situations in which the motivation is considered malicious by the speaker or writer. Just as e-mail spoofing can make it appear that a message came from any e-mail address the sender chooses, Caller ID spoofing can make a call appear to have come from any phone number the caller wishes. Because of the high trust people tend to have in the Caller ID system, spoofing can call the system's value into question.

It is amazing that such a crooked practice is allowed to go on!
Where are the feds when I need them????? I wrote to my US Rep...no response!

Bottom line: IGNORE IT and never give the other side ANY information. PERIOD!

I get 4 to 7 calls monthly asking for a Gary Dues, I keep telling them they have the wrong number.

The Do Not Call Registry is *NOT*...repeat...NOT for collection companies, surveys, etc. It is ONLY...repeat...ONLY for telemarketers.

Get a clue and don't be as dumb as them.
