Did not answer. Have been receiving spam calls daily from all kinds of different numbers AFTER adding myself to the Do Not Call registry. So beware, it doesn't work, at all.
"Social Media Experts" - I'm on the Do Not Call registry as well, but since joining, my spam calls have quintupled. I'm guess these hacks are using the Do Not Call registry as their call list.
Caller was in the middle of another conversation when the call connected. I could overhear him talking about tickling his boyfriends taint with a feather and something about marshmellow fluff. When he realized I was on the phone, he tried to sell me social media nonsense.
