superstamp - We never intentially missgrade a comic book, as this customer's "false grade" statement would imply.
To our knowledge, the books were in NM condition when shipped. It is unfortunate that this customer did not give us a chance to correct whatever problem there may have been. Instead, this customer just gave us the "Villian" rating and fired off an angry email to us.
We are always happy to work with customers, IF they are civil and have the maturity to handle simple situations in an adult manner.
