I get automated Telemarketer calls seemingly all the time.
They give me a option of press this number to have my number removed from their number list. That never works or has not so far, I get 'that's an invalid option', or some other bull.
I just don't bother trying those stupid remove options anymore. They don't work and the system on the other end knows it has found a live person.
