Called me on my cell, but left no voice mail. I will call them back after typing #67 (not #69) numerous times to waste their time. #67 blocks your number, and sometimes they will continue to answer. At that time I love to ask them stupid questions and lead them on
By pressing 9 you just confirmed there's a live person & confirmed time of day you answer. I've been using a great app called True Caller & have noticed a significant decrease in spam calls. It downloads all the numbers in the US that are BS which is a BIG list
