Actress Sonam Kapoor Ahuja has warned Uber users against using the ridesharing app in London after suffering "the scariest experience" with a driver in the British capital.
The actress, 34, said her driver was apparently "unstable and was yelling and shouting" during the journey.
"I was shaking by the end of it," she tweeted late Wednesday in London, tagging Uber, which responded with an apparently automated message.
"I tried complaining on your app, and just got multiple disconnected replies by bots. You guys need to update your system. The damage is done. There is nothing more you can do."
"The best and safest is just to use the local public transportation or cabs," she suggested.
A representative for the firm in India said it had no comment for now.
The Uber incident comes a week after Sonam Kapoor Ahuja criticised British Airways for allegedly losing her luggage for the second time this month.
Ride-hailing giant Uber has come under a storm of global criticism over its passenger safety record.
Hey guys I've had the scariest experience with @Uber london. Please please be careful. The best and safest is just to use the local public transportation or cabs. I'm super shaken.— Sonam K Ahuja (@sonamakapoor) January 15, 2020
The company lost its license in London after transport authorities said it had failed to fix a litany of safety issues - including at least 14,000 cases of drivers handing their permits to unlicensed friends or relatives.
It continues to operate in the city pending an appeal.
In 2017, a woman raped by an Uber driver in India filed a US lawsuit accusing the service of invading her privacy and defaming her character.
Last month, Uber released a report saying it had tallied nearly 6,000 sexual assaults in the United States - its biggest market - over the past couple of years. That included more than 450 cases of rape.
In France, the firm is under pressure from a viral campaign detailing sexual assault involving its drivers, under the hashtag #UberCestOver (Uber it's over).
