Ace Taxi is terrible. The wait time varies. Sometimes I request a driver for a certain time and he shows up 15 minutes early (and still charges me for the time that he had to wait for me to come out). The longest wait has been 2 hours. I was late that day.
Once the driver (supposedly) showed up to the location and sent that text thing they send but never called. We walked around my multi-building college campus looking for him for 5 minutes and then our reservation was cancelled and we waited another 30 minutes for a different driver. You arent told what kind of vehicle the driver will be in ahead of time. One time my mom got in a random car because she thought it was the taxi. Sometimes its a clearly marked van but sometimes its regular looking car.
Sometimes I feel unsafe in the taxi because the driver is using the phone or brushing their hair or driving aggressively or over the speed limit and I swear they sometimes purposefully take longer routes or make wrong turns to drive up the cost of the fare.
It seems sketchy that there's a screen thing in the car with a card swipe but sometimes the drivers have you swipe the card on their cellphone instead. One said to me "I don't want them getting my money" before he did it.
My partner is so fed up with this taxi service that she's opening an account with a bank so she will have a debit card that's compatible with Uber. Uber allows you to review your driver, tells you what kind of car the driver is in as well as a picture of him or her and there's always ubers in the area so you shouldn't be waiting for 2 hours.
