Who called from 7325556769

The caller ID said "New Jersey."  I figured it was another credit card scammer, but I answered it.  The person told me he was with a company that cleans chimneys from the roof, and they are talking with several of my neighbors on my street. He actually gave me my street name.  I have never had a telemarketer call me for a service before, so I thought this might be  legitimate. He continued explaining to me the problem with sediment build-up, etc. He asked me if I had any senior citizens living at my home.  I just said, "yes - several, and let me just interrupt you, as I have a maintenance company that I'll talk to about this issue."  WIth that he hung up on me...no thank you, no nothing.  I then called the number back to complain - well, this number is actually directory assistance in NJ.  It's amazing that these scammers can fake the phone number they are calling from.

I have been receiving calls from 555-6769, but with different area codes.  When I dialed these numbers I was told that the numbers were out of service.  
I have been letting the calls go to the answering machine, they hang up each time but not before the machine records it as a call.
Frustrated that these calls are increasing, I answered it.  The caller wanted to speak to my husband.  I refused and asked them to stop calling.  Of course they did not.  When I answered the next call they said my name (?!) followed by silence.  I am on the do not call list, what else can I do.  I don't think that I can block every area code+555-6769.  Any solutions?  Of course I am not answering the calls again.
It is suspicious that the same seven numbers are used over and over again with different area codes.  Seems suspicious.

What a crock, The chimney cleaning scam. I told the guy I would never do business with a company that used a fake number and no call ID name. He then told me he was calling to do me a favor! LOL! They were in my neighborhood and wanted to inspect and clean etc etc etc, I asked whose house in the neighborhood they were working on. He tells me they are right down the block. I again asked a name and he gave me two generic anglo names. I told him he was full of crap, I live in the middle of no where. I doubt we have a Block in the entire town. I would like to thank my Gov't for being completely useless in enforcing Do Not Call laws. What a joke

Called but did not say anything when I answered  This phone number now added to my blocked list.

Rc'd a ph.call from this number after 20:10pm in the evening. Said, "Hello" x2. No response. Who calls so late in the evening to sell their services?
Hung up on me. Fine by me. I do not normally speak to telemarketers or salespersons in the evening! Also, hid their I D of their business!
