Get a call blocker that lets you program only the numbers that you want to ring you. The rest will be automatically blocked. Since these pests are hiding somewhere making a dime by making their numbers show up on people's caller id's, they must be dealt with by using a powerful call blocker. Their criminal owners must be sued and jailed for setting them up.
I have tried all means possible to stop receiving 6 to 10 calls per-DAY from this #. If I ignore the call they call back 2-3 times in a row and never leave a message! I just answered a call (9:07 pm!) and begged them AGAIN to stop the calls (I have registered on every do not call list & they are calling my cell phone) and was told they want to refill my 'sedative medication' which I do not and have never taken such a medication. A Philippino told me "YES you do take the medication!" I tried to explain that they are calling my ATT cellphone and got NO WHERE! Frankly, if the calls continue I will NEED a sedative! They have called me at 5:00 am on a Sunday and 11:23pm on a Wednesday!!! Help!
Here's what you do on a cell. Save the number in your book. Name it "spam" or something.
Under ring tones, select none.
Now, you never hear them call again.
