Entergy customers in Mississippi, including those in Attala and Leake counties, can now sign up to get an $80 refund check. The money is the result of a settlement with the Mississippi Public Service Commission which ordered the company to offer customers a choice between a check or a credit on their bills. Those who want a check have until August 17 to go to Entergy’s website and sign up using their myEntergy account. Those who are happy getting a credit don’t have to do anything. It’ll automatically show up on their September bill.
