I dont answer, and then click block them, then google it. I gets tons of calls from all over the us and china so I just block them. I signed up once to an internet thing and they been hassling me ever since. Block block block!! This number is adddd to the list of spam. Then if I google the number and find out its legit then sometimes I unblock. But usually by blocking it gets rid of them. Also usually google says its spam when I have googled.
I've been getting calls non-stop Mon-Sunday from this number. Never picked up but glad I checked this site and saw that they are harassing many others as well. They are now on my auto-reject list.
