American Exteriors. They will harass you if you ever give them your phone number. They supposedly do siding and windows for cheap if you agree to advertise in your yard for them. I have talked to them numerous times and requested being taken off of their calling list, but still getting calls, very frustrating!

comes in as name unavailable and call is dropped upon answering.....

American Exteriors. These people have come to my door several times, and I've told them we weren't interested. I have told them before to also take me off of their call list but they still call. If someone figures out a way to get these people off your back please post!!!

Consider getting a call blocking device or phone.. You can google them and many are around $50.00 or so. If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.

I have had several calls, all unanswered. Discovered on my iPhone6 that I can block callers.

Go to "Recents"
Tap the "circled i" to the right of the listed call
Scroll down to "Block this caller"
Tap on "Block this caller"
