I answer & they hang up. I really would like for them to stop calling me

I keep getting a call from this person asking me by name.  I tell them I am not doreen and she is not here and can I take a message.  Than they hang up.  What bothers me is that they know me by my name.  This is disturbing.  I want this to end. Unfortunately I don't have a smart phone just a basic phone and I can't call block. Please do not answer from this number they are scammers.

Put the pest in your contacts list and give him the ring tone "no ring" or "silence".  That won't stop the calls but it will make them easier to ignore.

Verizon taught me that trick when I was getting collection calls for my namesake, Michael the Deabeat.
