I wish I could give them zero stars.
I've used Madison Taxi three times. Never again. The first time I called them, it took 45 minutes for the cab to show up. The second time it took an HOUR and the final time over 45 minutes. Then, all three times the cabbies took the longest possible route after I told them the fastest way. It ended up taking an hour or longer to get across town, with a total time of 2+ hours if you include the wait. It would have been far cheaper and much faster to take the bus!
They also have the *WORST* drivers in Madison. Two of the ones I ended up with didn't stop for a single stop sign and one sped through a couple red lights. That one tried to bully me for refusing to give him a tip! As if the $45 fare wasn't enough.
As a pedestrian, I've been nearly run down by their cabs twice so far. One of them screamed and swore at me like it was my fault he ignored the stop sign. If you're out walking, beware of these cabs!
I have emailed the company to complain and was completely ignored by everyone from the "safety" manager on up to the CEO. They don't take safety concerns seriously and really don't care what their customers think of them. I am NEVER calling these guys again and I strongly urge anyone needing a cab to call one of the three other cab companies in town; you'll save time, money and frustration.
