no cars 15 blocks from base wow close it up

I just had a terrible experience with dekalb car service a few minutes ago. I called for a ride to the airport and was told 5 minutes. 15 minutes later there was still no car and the operator told me to look outside he should be there or pulling up shortly. 10 minutes later I called back and he apologized and said 3 more minutes. After 10 more minutes I called an uber, which showed up in less than 5 minutes. I called back and told him to cancel the car and that it was a major inconvenience and the operator was nasty and hung up on me. Never again, long live uber!!!!! Terrible customer service and this could cause me to miss my flight
