Question about refunds

Hi,

I’m trying to get a refund. Last week I noticed that I was charged for this AWS service. For context, I signed up as part of a boot camp and was told that this was the free option which is the only reason I provided my payment information.

FYI, I understand this is probably not the right place to post, but after a quick search through my menu options I couldn’t find a customer service email or phone number to ask this question.

Please let me know who to talk to to discuss refunds. Thanks, Ben
