AAAGGGHHHHHHH!!!

Friday morning, I have received an email telling me I have made a mistake when debited the SE for two Chargebacks on th UK queue as valid support was in another case (how am I supposed to know that???). So I have to do a debit reversal in GUSLD, which I can't even remember how to do and no one even left any Case Notes or axp refs. And it is my fault for being rubbish, but the worst thing is that you don't even have a clue what I'm talking about!!!
