I got five calls from this number. Very annoying! How to stop it?

No idea, and yes quite annoying i put my phone against my speaker on full may only be 70watts but ive tested it out with a friend cause some dmg to his phone, im hoping for the same, or better yet, them not trying to muffle the phone when its answered my brother heard his phone blow, outside the house across the street i hope they had a headset on and were listening REAL close, and im gonna do that EVERY time i get a call from them, just on the offchance that itll get them to stop calling me

yea i keep getting calls from them too!

no wonder why keep calling me every time i tried answer him with answer his phone..how can i commute him..no text..i am deaf..does he know me that i am deaf...no wonder..must be he is scum...

i think mine started by a free ipad giveaway, that i made the mistake of putting my number up. that im kicking myself for. iv had several calls that i have not anwsered. my concern is where else is my number going to go.
