Muffy
I think the scammers often just dial the next number so getting on the do not call list doesn’t help with them.
I had one caller who knew my name, phone number, address and age. That was concerning and after having had a credit card number stolen I think I might go ahead and freeze my credit as the warning after illegal use of credit card doesn’t last all that long.
They are a royal headache – especially when they “spoof” a local phone number.
