Uber faced the wrath of Twitter after it responded to a customer complaint by calling them the n-word.

The company's official Twitter support account responded to a customer complaint who was asking for a ride refund. Uber apologized but instead of using the customer's name, they used the word n*gger.

“We’re so sorry about that, N***er! Please send us a DM with your phone number with additional details of your concern, so we can connect," the tweet read.

Shortly after, Uber made the following statement, but the tweet had already gone viral:

“We’d like to sincerely apologize for the offensive tweet that was sent earlier. We’re investigating what happened to make sure it doesn’t happen again.”

A spokesperson for the company later addressed the incident with Mashable:

"We apologize for this offensive tweet and are disappointed our process to prevent something like this from happening was not effective here," they told Mashable. "Our support team is taking additional steps to help ensure this doesn't happen again."

But according to some on Twitter, the guy initially had his username as the n-word and then changed it before many were able to witness it, so it may not have been Uber's fault entirely:
