There was a misunderstanding about my order of 500 CDs. I had requested a barcode in an email message, and was told it would appear on the CD, but it didn't. It was no big deal, but when I pointed out the mistake the admin guy became very abusive.
I responded in kind, but then he took it a step farther by posting edited versions of my emails in an attempt to slander me.
For example:
1) he called me "white trash"
2) I responded by asking why he'd say that, and if he was ashamed of his ethnic origins... then I said, "I hope you die" - pretty harmless.
3) he edits my email and posts it on his site under the title "more death threats and racism from slambango"
I should sue them.
