If payment remains unpaid, a disconnect letter is mailed giving 10 additional days; service may then be disconnected. Reconnection requires full payment of past-due balance plus a $25 reconnect fee per service and possible deposit. Contact customer service promptly if you anticipate difficulty paying—Quadvest can connect you with local financial assistance organizations.
