Interesting problem

I queried an agency at the end of July. They asked for a few chapters which I sent. By last week, I hadn't heard anything so I wrote and asked if they wanted to read the manuscript based on the partial. I got a rejection and thought that was the end of it.

Today I have recieved a request for the manuscript from the same agency. The problem I've got is what I do next. I did submit to a name but none of the replies have come from any name, just the submissions department. So do I send the manuscript and hope the person who rejected me doesn't get it or do I just forget about it?

This is quite a nice problem but I really don't know what to do next.

Thanks for the replies. I've never got this far so this is all new to me.
I'll let you know how it goes.
