I know that I can block calls on my galaxy s9, but is there a way to block not only the telephone number use for this specific time, but to also block all other telephone numbers used by this company. Almost all of the calls thatIdo block areset upto auto dial and have multiple lines, sometimes up to the 100s. So it is virtually impossible to block these calls that are annoying, frequently unrelated to my life (both business and personal), repetitive, and time consuming. Not to mention the fact that I so often wonder exactly HOW much of my personal, private information that these companies have about me. I keep telling myself that someone out there knows a way to make my request possible or at least to create a good response that may deter some of the calls. My nephew tells the telephone "intruders " that in addition to their name, he requires a $25 returnable service from the caller or their employer using PayPal or Venmo before listening to their sales pitch. He has also offered to participate in surveys for a nominal donation from caller/company to any one of five or six charities. While it may be good for my sense of humor, it doesn't stop many. I eagerly await all of your thoughts and suggestions.
