RALEIGH, N.C. -- North Carolina consumers keep complaining about health insurance, medical providers, and health products and services.

Attorney General Roy Cooper's consumer protection office says that for the fifth year, the most common complaints it received involved health care. Consumers often complained about medical billing or collection practices, overcharging for medical services, and getting charged for supposedly free weight loss products.

Behind health care were complaints about lenders and telemarketing fraud, which both saw an increase of gripes last year compared with 2008.

The list of top consumer complaints has been consistent for years and includes credit and collections, health club memberships, car repairs, home furnishings, telecommunications, and home repair.
