Hidden costs Used curb for the first time this past weekend. Midtown to LGA. Booked the night before and chose it over Uber because it appeared to be about $25 cheaper. My $45 quoted fare quickly turned into $71 wiall the add-ons. Same price as Uber at the end. And beware that it defaults to a 20% tip unless you go into your account and change it. Found out too late.

It just doesn't work! Like many other reviews, I am disappointed that I can't give less than one star. When using Curb only to simplify payment, the transaction went through to my credit card but did not go through to the taxi company. They showed that they didn't receive the payment even though they could see that it went through to my card, and insisted that I still needed to pay them. I called the taxi company, Metro Cab in Boston, and they said this happens all the time and I needed to pay them and get the refund from Curb. I thought Curb would save time and money not cost more time and money. The taxi company told me I shouldn't use Curb and I suggested that they shouldn't advertise for it in their vehicles if they were going to force me to deal with a refund when it doesn't work. I will never use Curb again and would encourage all taxi companies to drop the system if they are going to dump the problem issues onto their customers.

Not dependable Not dependable - scheduled a cab 8 hours in advance to make a flight. 13 minutes after the cab was scheduled to pick me up, I received a text saying there were no cabs available and I would have to reschedule. The app claims you can easily schedule your ride - and it is easy to schedule. Just don't count on them being there as promised. Uber and Lyft have this perfected - Curb is further proof why old-fashioned cabbies are on the way out.

HORRIBLE HORRIBLE. The a-hole driver who accepted my request sat at the (wrong) end of my block for a minute or two, wouldn't answer his phone when I called (twice), and then just suddenly cancelled the ride. A full twenty-five minutes later, a replacement driver arrived. I'm now massively late for a hospital appointment, will likely have to re-book, and have $50 of wasted fares on top. There's no way to complain about the a-hole who wrecked my day. Angry and disgusted. Horrible service, horrible system where drivers can just suddenly change their mind with no explanation. I'm boiling mad. Zero stars would be more appropriate.

1st time user- we were hit with a 30%… 1st time user- we were hit with a 30% up charge for van at MIA airport without notice for 2 person ride and tip would not allow custom amount - defaulting to 20%. Contacted Curb support without any luck for refund. Going back to Uber.
