The owner of two California maid service companies has been charged with double-billing customers who wrote negative online reviews.

Los Angeles city prosecutors filed seven counts of identity theft on Monday against Steve Yun. Prosecutors claim he illegally obtained personal information from four people in the process of overcharging their credit cards.

Yun owns West Coast Maids and California Maids, which provides online referrals for maid services.

Prosecutors say Yun contacted customers who wrote negative Yelp reviews and asked them to remove the reviews in exchange for refunds, then double-billed some who refused.

Yun could face up to seven years in jail if convicted.

He wasn't arrested, and it's unclear whether he has a lawyer.

Yun didn't immediately comment on the charges.
