ok my email quote above was edited by WebmasterWorld to comply with their TOS so here is a synopsis of what the email said:
They Thank me for my email. They apologize for any confusion. They understand that I would like a refund for the amount of charges accrued due to a technical issue, instead of a credit. At this time, they are unable to provide a refund of the charges accrued. They will still automatically credit my account for the additional advertising activity which my campaign accrued after the campaign was paused.
I never thought Google was capable of this.. I guess you live and learn ..
btw - I hope that this synopsis is acceptable under the WebmasterWorld TOS, I don't mean to offend anyone by posting it ..
