As the user tells BuzzFeed, she had originally booked a car to take her to meet friends for Sunday brunch. Admitting she suffers from the occasional anxiety attack, she decided on the day she'd be more comfortable walking to her destination, and so canceled the booking a few minutes before it was due to arrive. She thought nothing more of it, but today discovered the driver in question left her a threatening and aggressive voicemail message following the cancelation (you can listen to it in full below). In it, the driver insults her several times and repeatedly tells her not to "do [that] again," before saying "otherwise, I'll cut your neck."

Understandably, the user's rattled by the verbal attack, especially since she ordered the car to pick her up at home, and has launched a complaint with Uber. The company is now on the case, and a spokesperson has issued this statement in response:

"We have spoken to the rider to ensure they are OK and encouraged them to report this to the police. The driver has been immediately suspended, as is our policy, and we are investigating fully."

It's yet another controversy Uber could do without, and it'll no doubt fuel further criticism of driver background checks, which have been deemed inadequate in the past. But, more importantly, it leaves users and critics alike asking: do a few bad apples spoil the bunch?
