Who called from 3017123398

Same here, they called and ID says wireless caller.

Not a scam!! Got a cleaning from them yesterday, very knowledgeable technicians.

Just got a call from the 800-340-9610 number.  

I answered, and the woman after realizing that someone had actually answered the phone clicked on and said, "Mrs. Jones" (not my real last name).  I said, "uh...no, MR. Jones".

She said, "I'm calling about the chimney cleaning there at *name of my street*"  I said, "uh...I don't have a chimney"....she said, "that's a good reason to not be interested, have a good holiday" then she hung up.

2 calls in one day. I picked up the phone both times and no one was there, and then they hung up.

I keep getting calls from this number but do not answer them.  Caller does not leave any message. I went on White Pages.com to find the number and it said that the number was a landline in Frederick, Maryland.  Very often the phone will ring again immediately after this "caller" hangs up, but the second time the caller ID says "Blocked Call."  Don't know if it's the same caller, but I suspect it is.
