Do not use unless you have CASH! Driver had to run my car through an old-school swipe box. Then when he sent it to the owner(Michael) to do the electronic transaction, he charged me twice! In an effort to get my money back, I had to talk to his bank. He refused to believe that there was a second transaction. Eventually, I contacted my bank and had the transaction disputed. What a MESS! Never again will I use this service when I visit Mobile on business!
