Notice and timing
How delinquency is handled
Grace period after the due date
Payment received by the 24th of each quarterly due month avoids interest; the source does not state a separate grace-period rule beyond that date.
Late-fee calculation
Interest applies when quarterly payment is not received by the 24th of the due month; the reviewed page did not state the current percentage.
Disconnection timeline
A dedicated this detail was not publicly posted. The reviewed billing page did not state a fixed disconnection calendar.
