RALEIGH – The Better Business Bureau for Eastern North Carolina has assigned an “F” to Cary-based Epic Games for complaints filed about its games, including the globally popular Fortnite.

The “F” is “due to unanswered consumer complaints,” the BBB said in a statement issued Wednesday morning.

The F rating is the lowest assigned to a business by the BBB. A+ is the highest.

Some 279 complaints have been filed over the past three years, all but eight of those coming over the past year during which Epic launched Fortnite.

In the announcement, the BBB says 247 complaints “have gone unanswered.”

WRAL TechWire has reached out to Epic Games for comment.

The success of Fortnite has made the company worth several billion dollars in value. according to estimates from Bloomberg news.

“A majority of complaints submitted to BBB against Epic Games deal with customer service and refund or exchange issues,” the BBB said.

Epic offers Fortnite for free although other versions are available. Players also can buy accessories online.

“BBB has attempted to contact Epic Games on numerous occasions, but the company has failed to respond,” the statement noted.

BBB’s announcement included two statements from complaints:

“Epic Games failed to protect customer security, resulting in several unsanctioned charges over mine and my partner’s account.”

“There is no phone number or proper email response time to return my unauthorized charge of $160. Nobody will answer, and I feel cheated.”

BBB notes that its “ratings are not a guarantee of a business’s reliability or performance. BBB recommends that consumers consider a business’s BBB rating in addition to all other available information about the business.”
