If you are coming here and you have Charter Communications telephone service, type *60 at a dial tone and it takes you to Charter's call blocking service (all automated). From there I had to activate my service by pressing "1", then I had to add this number by typing in 281-872-6247. It will confirm the number then you press "6" to exit and end the call. I did that and I have not received a call from them since.
I also added number 805-219-6220 to my block list, which is also on this website with other reviews stating their as shifty as this phone number was.
Missed a call
