Last year, I filed a complaint with the NYC Taxi & Limousine Commission against both Lyft and an individual driver after the driver refused to pick me up in the middle of Manhattan but refused to actually cancel the ride. I eventually gave in and canceled the request. Lyft refused to refund the cancellation fee. I ended up getting a chargeback from my credit card company.
I submitted the driver's text messages to the T&LC as evidence and eventually got a phone hearing -- Lyft and the driver were required to appear in person. Lyft failed to appear and got a $1,000 fine. The driver showed up but was found not responsible for lack of evidence. It was a complete waste of time.
We'll be stuck with this until regulators realize that there's a pattern of abuse and start cracking down.
