Is anyone else fed up with calls from this group?  They keep changing phone numbers and never leave a message.  It's pretty hard to report them when they don't use the same phone all the time.  The only thing that seems to stay the same is the "BCSF" although I have noticed that even that seems to indicate several different groups.  Also, it seems that they aren't robotic calls, so NOMOROBO doesn't block them.  Any suggestion on how to get rid without turning phone off (not practical with 93 yr. old mother) or cancelling a number I have had for 40 yrs.?
