900 Credits Burned on Client Account Due to Waterfall Enrichment Miscommunication

hey i accidentally burned 900 credits without knowing on one of my client accounts. I thought the waterfall enrichment phone finder would stop running rows if it found a valid number, but it didnt. Somehow i burned 900 credits on 42 contacts in a sheet. I can send a screenshot of the usage, and the comparision between the sizes of the tables i exported for the 42 contacts. Im doing ABM for reference, hence the 42 contacts only.
