Canvas ridiculous bill

Question

Hi there,
I noticed that my canvas has been running in the background as I didn't logout. Although, I just opened canvas to see what feature it offers with anything untouched without knowing that if  I don't logout I'd be charged $1.9/hr which is ridiculous since I absolutely used nothing. And now my bill has risen to $150 for the services I didn't even use.

I saw in free tier description that canvas offers 160 hours/month for session time. Can I know why am I charged if it's free. Also how can I raise a ticket to strip that charges off my bill? I'd greatly appreciate your help. Thanks!

Answer

Especially using Free Tier entitlements, it's wise to setup you budget first to avoid this unforeseen situation.
With AWS Budgets, set custom budgets to track your costs and usage, and respond quickly to alerts received from email or SNS notifications if you exceed your threshold.
Set up custom actions to run automatically when a budget target is exceeded. 
You can use daily/weekly & monthly budget
