Crazy lady from Craigslist

So my husband and I had a crib we were doing to paint and fix up for our son we were expecting. Last week we found out we had lost him and had to have a d&c; to have his body removed. It has been a very hard week for us. So we decided we did not want to keep the crib anymore so we posted it on Craigslist to sell it.

This was my post I made. Simple and frank. Pretty quick I got a response. Everything was set. The woman agreed on a price. We set a time. Her husband came to check out and pick up. He liked it and pairs us and left. Next thing I know I’m getting nasty threatening text from this crazy lady. What should we do about it?
