Kansas has fined AT&T for overcharging the state’s Lifeline program for a third year in a row.

The Wichita Eagle reports the Kansas Corporation Commission fined the company $15,000 for overcharging the state’s Lifeline program by about $100,000 last year. AT&T received $476,000 in Lifeline credit last year.

AT&T also paid $4,750 in December for overcharging more than $83,000 in 2012 and 2013.

The fines stem from AT&T erroneously claiming Lifeline credit for customers who didn’t qualify for the low-income phone service subsidy.

Records also show the phone company has paid back the money it overcharged. The report also noted that in April, the Federal Communications Commission levied a $6.9 million fine against AT&T and its subsidiaries for Lifeline violations nationwide.
