Thank you for giving Amazon Web Services a try. I'm sorry you received a charge you were not expecting. I see you closed your account on 11/08/2013 using our self-help service.
I'd be happy to explain to you how you accrued the charge of $116 for October 2013. In reviewing your account, I see that you launched a cc2.8xlarge Windows Spot Instance in the US West (Oregon) Region.
To help with this charge for November, I have applied a one-time credit of $65 to your account, and this should cover for the charge you've accrued for this instance up until you closed your account"
ну и там дальше они пишут какая я молодец вообще в принципе и все такое!
