Google's AdMob Refunded Several Payments

Over the past few days we have had some weird experiences with Google's AdMob.  They refunded several hundred dollars worth of payments that we made for marketing campaigns; and then today they reversed some of those same payments.  The only thing I could find online about this issue was in a forum:

Has anyone else had this same issue?  I can't find any contact information for them either.  Sounds like a major screw up to me :-(
