Stop bill collectors from calling....?

my cell phone asking for someone else. I just got off the phone in a yelling match with thhis idiot on the other line, she called and asked for someone and I politely told her not once but twice my name and that this was not the correct number for the person she was asking for, I told her twice that she had the wrong number, so instead of saying okay she rudely replies look we can do this the easy way and you can give me the number or I'll keep calling, so I lost it and let her have it, what can I do to stop them from calling me when I have told this woman that they have the wrong number?
