Stop calling me

Strange noises when I answered, like someone was purposely doing this, so of course I didn't call back, and I got pretty mean. Its the first time I have gotten a call from this number, and I regularly use some sort of area code look up if I don't recognize a number. Since this was to my cell phone, I have two different ringers that I use to distinguish unknown and unwanted callers from folks that I love to talk to. Sadly, being on the do not call registry doesn't help prevent these calls.

they called me on my lunch break telling me I have a $9000 grant and they needed my checking/savings acct. I told them I didn't have one and I am on lunch and was not interested. Then the lady (who had a really thick accent) starts talking crap about me to her co-worker. I am not about to give someone my acct number for anything. If its a grant and I can do whatever I want with it why did she tell I could not use it towards going on a vacation or go gambling with it?

This number called my cell phone numerous times today, every 30 minutes on the dot, no message left., So, before I blocked it I thought I would answer. I had to say Hello twice, then this male voice asks for me by my name.  I told him she wasn't home, "what do you want?"  He replied "I need a girlfriend."  I said "oh, really? Go F*** yourself" and hung up. I do NOT us that word but it seemed necessary in this case. That number is now blocked.

Called about grant referred me to call another number to get info. Wants me to pay 230.00 iTunes card to get 9000.00grant.
