I did not ans call, not knowing who was calling

I just received a call, after not answering the original call. When answering a call later , what I thought was a local call, it was from the 2133 number stating, by a recorded message, that a (blurred name)was calling in response to a previous conversation we had regarding an (Electro -light messaging system)? for our church and he wanted to know the status of our interests and how he could help.. I have never had any such contact with him.
