PORT ORANGE, Fla. -

Thousands of residents in Volusia County won't get their water bills this month because Port Orange officials are delaying the October bills to check their accuracy.

The delay comes as a response to a slew of recent utility problems in which a rate change was entered incorrectly into the computer, causing the city nearly a million dollars.

Customers in Daytona Beach Shores were undercharged more than $800,000, investigation found. Some customers were overcharged $200,000 since 2009.

The city also learned meter readers were reading the wrong meters in the Spruce Creek Fly in community resulting in customers being overcharged $500,000.

Then a customer service manager who was suspended as a result of the incident was caught on video removing documents from her office.

The city said because of the billing delay, payment due dates will be extended. The bills are expected to be mailed out on Monday.
