Request to Restore Used Credits and Charge for Monthly Renewal

Hi - our credits were meant to renew today. All 10k have been used it seems (within 24hrs of getting renewed - it says next cycle is Jan 17th). We haven't been charged but we'd also like our credits back. We have hundreds of tables with automations so it's hard to pinpoint which table is using the credits. As soon as we find it we will turn it off. Anything we can do here to get the credits back and get charged for our month as well as remove the credit consuming tables we have that are running? Thanks!
