bad calls all the time thru day--going on for couple months

I keep getting calls from them two or three times a day and it's so annoying so finally I picked up and they wouldn't tell me exactly who it was. so sick of this!

I just got ANOTHER call on my cell from this number.  They usually identify themselves as a business opportunity and ask if I'm still interested in making money.  Well today I told them no ...that i make to much money as it is (haha)...and he said I bet you do... you just need to shut up [***]!!  I have never tried calling his number back before...but today i did. Got the busy signal.  I get this call at least 3 times a week. I usually just hang up on them...but todays call really made me mad!  You people suck!!  Whoever you are!! Get a life!!

The number 4802829111 keeps calling me and hanging up upon pick up or first ring.

They call me every day and not leave a message.
This is getting on my nerves!!!
