Who called from 2403181607

Repeatedly asked the not to call report to FCC as unwanted calls and I have non pub phone line and a disabled handicapped elderly person, they keep on calling,

Keep getting calls from this number. They are not a cleaning service at all. I have blocked them.

They called on my listed line this time, but the Caller ID name came up blank.  (The number itself showed up.)  I've seen that kind of thing happening more and more often recently.  Beware!

When I picked up the phone I kept saying huh in a whiny voice. Kept them going for a good 3 minutes!

Just called, listed as "Duct Pros". When will these annoying calls stop? Washington's greatest joke on the American public, the "Do Not Call" list!
