Green Man Gaming has issued a response following numerous customer complaints of trouble redeeming or receiving codes for Titanfall 2 and Battlefield 1.

Though the online store did not identify what the problems are with getting codes to customers, in this statement, Green Man Gaming said it was bringing on additional customer service staff to work through tickets.

"We'd like to sincerely apologize to all those customers who we've been slow to respond to," Green Man Gaming said, noting that demand for the two games on the store "has been unprecedented."

The subreddit for Green Man Gaming is teeming with reports of invalid codes, unreceived codes and, most recently, troubles logging into the site itself.

Green Man Gaming has had issues distributing and redeeming keys for popular games before. And in 2015, the site got into a row with CD Projekt Red over deeply discounted codes for The Witcher 3, which the developer said it did not sell to Green Man Gaming.
