The process for electricity service cut off is as follows:
You will receive your normal bill via the United States Postal Service.
If late, a late fee will be assessed, and a second "cut-off notice" will be mailed via USPS letting you know a cut-off date has been schedule.
If the bill has not been paid by that date, service will be cut off.
No one will ever call and demand payment.
Customers who receive threatening calls demanding payment should report it immediately to customer service at 865-273-3456 or alert the police at their non-emergency dispatch number 983-3620.
