Spending limits use the UTC calendar month and reset at midnight UTC on the first day. That moment can fall on a different local date or time. Reserved charges also count against available budget until consumed, released, or expired.
Compare the displayed month and timestamps using UTC before treating the total as incorrect. Credit purchases and direct Meta charges are separate from Polymorfa number-service spending. If the new period still shows an unexplained commitment, report the scope, displayed values, and time to support instead of deleting the limit.
