Here's what I wrote back to him / them:
Umm, I was not aware that someone from this team told you to get peace with Epsilon. If that's really the case, then I apologize for holding your team to the prior agreement. All I can say is that the alleged communication to you was never made known to any of the other Piffles. Honestly, this is the first I've heard about it! Please supply a copy of all the correspondence you have relating to this - I'm going to feel really badly if had been miscommunicating over these past few weeks!
