I'VE HAD SO MANY BAD CALLS, THAT ONE OR TWO PEOPLE WOULD CALL MORE THAN ONCE A DAY, THE PHONE WOULD RING SO MANY IN THE DAY AND IN EVENING THAT I FOUND A PHONE BLOCKER AT AMAZON ITS CALLED SENTRY PHONE BLOCKER FOR ABOUT 29.00 DOLLARS AND I'LL TELL YOU ITS AMAZING IT WILL HANDLE UP TO 9999 BLOCKS. WHAT I DO IS LET THE PHONE RING WHEN IT STOPS I HIT THE REJECT BUTTON AND WHEN IT CALLS BACK AGAIN I GET ONE RING AND GOES INTO REJECT MODE , NOW IF YOU HAVE CERTAIN NUMBERS LIKE YOUR AREA CODE AND SOME OTHERS LIKE 800 AND SO ON. ILL PICKUP THE PHONE AND IF ITS RIGHTEOUS CALL I HIT ACCEPT AND IF ITS NOT I HIT REJECT. I HAVE 29 ACCEPTS AND 98 REJECTS . I HOPE THIS HELPS YOU OUT.
