The home improvement retailer pulled the tweet and apologized on Twitter, saying, "We have zero tolerance for anything so stupid and offensive. Deeply sorry. We terminated agency and individual who posted it."
In a statement provided to ABCNews.com, Stephen Holmes, director of corporate communications, said, "We have zero tolerance for anything so stupid and offensive. The outside agency that created the Tweet and The Home Depot associate who posted it have been terminated. We're also closely reviewing our social media procedures to determine how this could have happened, and how to ensure it never happens again.
Customers responded to the apology on various social media sites.
"Deflecting blame and now all is hunky dory? Hmm," one Facebook user wrote. "So even though you hired the firm responsible for the shockingly racist tweet, you bear/accept no responsibility? Here's to hoping your company uses your one 'do over' wisely."
Another Facebook user wrote: "Very respectful way for you to respond to that offensive tweet. I will continue shopping at the Home Depot. Thank you for firing whoever posted that!"
