If you do online gaming the Acadiana Better Business Bureau is warning of an 'F' rating been given to the Valve Corporation doing business as 'Steam'.

Valve Corporation offers computer game software publishing, internet gaming and operates as an online video game dealer. The company earned an 'F' rating after the BBB received 715 complaints with a failure to respond to 503 complaints. 17 complaints were never resolved and the business failed to resolve causes of the patten of complaints.

Consumers claim the games bought do not work or have an invalid CD key. Consumers also claim the company blocks users from accessing their library of games, does not correct credit card charges or does not respond at all.

The BBB reminds you to always pay with a credit card when shopping on line because purchases are protected by the Fair Credit Billing Act.

If you have a problem with an online purchase you can file a complaint with the BBB at bbb.org or calling 337-981-3497. You can also file a complaint with the Federal Trade Commission at www.ftc.gov.
