Well first of all I want to say I feel sorry for you, and I hope that you et your accounts back!
If all that you described above is true, this sounds for me like someone on blizzards site screwed up, and this would be resolved by calling/emailing them.

If you want to be sure about your used HKN-script, you perhaps may want to post it here, so that we can have a look at it and see if its ok or anything is wrong with it.
