Uber is refunding passengers who used the service after the London terror attack

Uber is sending a message to its passengers—use the app in times of emergency, regardless of the surge you see.

The ride-hailing giant refunded the rides of all customers who used the service during the London terror attack on Saturday within the affected areas. That included tens of thousands of passengers, according to a statement from Uber.

The company also said it eliminated surge pricing after finding out about the incident.

"As soon as we heard about the incident we immediately suspended dynamic pricing all around the area of the attacks—and shortly afterwards across the whole of central London—just as we did following the attacks in Manchester and Westminster," reads the statement, attributed to Tom Elvidge, general manager of Uber in London.

Uber has previously taken heat for allowing surge pricing during terror attacks, most notably after a bomb injured dozens of people in New York City in September 2016. Other times they have canceled surge, for instance around the Paris terror attack in November 2015.

The company, which has had a rough stretch that has included accusations of deceiving local authorities, stealing another company's technology, and having a toxic workplace culture, initially eliminated the surge but then decided all rides taken in Central London during the attack were to made free and refunded all affected passengers.

"We are also ensuring all rides from around the affected area were free of charge. Our team is also working with the Metropolitan Police to help them get any footage from drivers who were in the area at the time," the statement continued.

Uber also donated to #OneLoveManchester, the benefit concert organized by Ariana Grande.

Instead of coming up with a number to donate, Uber said it would match fares to and from the arena.
