nashville cab Allied cab The worst most unreliable taxi service ever nashville, Tennessee

I called this taxi service at 7:24 am and was told a cab would come in 5-10 mins. At 7:34 I called back to check on the status and was told they were still looking for a cab to dispatch, meaning no one was on their way. I called back several times (but no one knew anything) after the other cab companies were honest enough to say they either didn't have anyone or that there would be a long wait time. They finally sent someone after 8 o'clock. They are so I poorly run I don't know how they stay in business.
