You had best reconsider your rush hour Uber ride to Tim Horton's, because that last infusion of coffee and Timbits might cost you more than you anticipate -- at least until Uber recognizes the error.

Twitter user Emily Kennard reported on Dec. 9 that her friend was recently charged CA$18,518.50 ($14,400, directly converted) for a 20-minute ride through Toronto. The unnamed friend apparently attempted to dispute the charges and was initially rebuffed by the beleaguered ride-hailing giant.

Only after Kennard took to social media did Uber cop to its mistake and refund the ride. "There was an error, and we have provided a full refund. We sincerely apologize to this rider for his experience. We have safeguards in place to help prevent something like this from happening, and we are working to understand how this occurred," an Uber spokesperson told The Comeback.
