I've been getting a lot of calls from my area code and exchange on my cell.  We have the same cell phone, although we have moved and are no longer in this area code or exchange.  I again received a call from 516-445-9845, so I thought maybe it was someone from my old neighborhood, so I used a different phone to call them back.  Someone did pick up and when I asked who I was speaking to, i told them that I had received numerous calls from this #.  They insisted I tell them who I was - I did not tell them.  They apologized and same it must have been a call in error.  There was a lot of clanging (of pots/pans/dishes being washed?) in the background.  I have blocked this #.
