Why was credit deducted even though my fax failed to send?

Credits may be deducted from your account for unsuccessful fax attempts due to telecom operators charging for call duration, regardless of the fax transmission's outcome. To understand the specific costs incurred for any fax attempt, you can log into your account, and go to the Sent section. By selecting Fax Status, you can view a comprehensive breakdown of these operator charges. This feature enhances billing transparency for all your fax transmission attempts.
