This number has been calling me 3X within a week which they wud stop calling

I get 5 calls a day asking for Marcy, I've asked them several times to take me off their calling list.  I do not know a Marcy but they continue to call at ALL times of the day/night.  How can I make it STOP?

call all the time

I have received 4 calls so far today from this number. I haven't answered, but it is really irritating.

ive gotten these calls, asking for a james, mark, anthony, and a bernice..... my name is none of these, before i could tell them to stop calling they hang up... ive found out from a friend that if you tell them that your phone line is meant for business or business transactions only, they tend to stop calling
