why are they allowed to do this.  Does it happen because of the phone plan?

and i guess you just have to deal with it cause ive tried everything to put a block from that # but nobody seems to be able to help. But i wouldnt doubt it if its some kinda scam.so dont do anything if they ask. but for myself i just get no comment and when i call back i get # disconected.......Maybe its a GHOST !!!!!!

i am getting the same calls from the same number and place, they told me i won a shopping spree, and all i had to do was pay $1.95 for the shipping of the package. i told them i was not interested, and hung up, they still call, but now they hang up, it is crazy how many times they call during the day.

THE #(712-429-0248) CALLS 3 OR 4 TIMES A DAY FROM 7AM TO 11PM. WHEN WE DO ANSWER THEY HANG UP,IF WE TRY TO CALL THE # BACK WE GET A RECORDING THAT SAYS THE # HAS BEEN DISCONNECTED OR NO LONGER IN SERVICE. WE ARE IN TEXAS AND OUR LOCAL POLICE DEPARTMENT HAS TRIED TO CONTACT THE # EVEN THROUGH VERIZON AND NO ONE CAN TELL ANYONE ANYTHING. THE NUMBER IS ONE OF THOSE FAKE NUMBERS FROM A VOICE OVER SYSTEM AND FROM WHAT LITTLE I HAVE BEEN TOLD IS THAT THE PEOPLE THAT CALL FROM THE NUMBER ARE SCAMMERS AND HIT THE ELDERLY PEOPLE REALLY HARD BY GETTING A CREDIT CARD #. OUR NUMBER IS ON THE DO NOT CALL LIST SO WE HAVE NO IDEA ON HOW THEY GOT OUR NUMBER.
BE CAREFUL AND WATCH CALLING THE NUMBER BACK AND REALLY DO NOT CALL THE NUMBER BACK FROM YOUR COMPUTER! THEY WILL ONLY HACK YOU!!!!!!!!!!!!!!!

We recently moved here from another state and just as soon as we got phone service we started getting several calls a day from this phone number 712-429-0248...the caller ID says SLOAN,IA. I am on do not call list but haven't been on the 31 days that is required before i can report them. They are calling 5 or 6 times each day and it's getting on my last nerve.
Does anyone know how to block it?
