My cell company doesn't allow me to block calls. What I do is assign a special ring to them bookmarked as Scam and let those calls go to my very long winded insane message answerer. If I answer by mistake I will waste as much time as possible ordering everything they sell. I make them explain everything several times as I keep getting confused. Kept one guy on the line for 52 minutes then asked if he wanted to talk to my Father as I was 8 years old. .......I'm Retired I got plenty of time to waste.
Obvious telemarketing call. My number has been on the national "do not call" list for several years but these JERKS don't care. They call anyway because ever though they get reported, nothing happens to them. Bet they would stop if someone hunted them down and put their product where the sun doesn't shine.
