I just got back from being out all day.  I had been in contact with n4ru and to quote what I told him over Skype.

[8/29/2013 12:15:35 PM] Ms Bitcoin: I will definitely work with you if the problem is something i caused.

I buy a lot of bitcoins with MoneyPaks and also sell some bitcoins for MoneyPaks, bank deposits and other payment methods.  Not once has there been a problem with a transaction of mine where I did not make sure my trading partner wasn't 100% satisfied with the resolution.  For n4ru to contact me, have me tell him I would work with him to resolve his problem and then within 6 hours have him call me a liar and a scammer is totally uncalled for.  I am still hopeful that n4ru and I can resolve this amicably.
