Didn't left messaged

They call repeatedly and hang up.  Take me off their call list!

Yet another idiot  from India wanting to offer me special grant monies for the school that I am NOT ATTENDING or reduce interest rates on the credit cards THAT I DON'T HAVE!!  He told me to "go
f¥<€ myself"

....

I did not answer the phone with hello. I yelled WHO IS THIS? He said Calvin. I yelled what do you want? He asked to speak to me by my first name. I yelled NO and stop [***] calling here and hung up. Reason being..... I don't know anyone in Washington D.C., and they call at least 10 times in a row everyday when I am trying to sleep as,I work overnights. They do not leave a message don't must not be important.
