On more than two occasions the Yellow Cab taxi drivers have accosted me for using a credit card to pay for their services. The two individual taxi drivers became upset and raised their voices when I asked to use my credit card to pay for my taxi rides. Both taxi drivers tried with no success to say that their credit card machines weren't functioning. They eventually allowed me to use my credit card, but with much disrespect. I did make a complaint via telephone with a dispatcher and received an apology. Although I received an apology, I believe that customers and the Yellow Cab management should be aware of their employees' poor customer service and dishonesties. I haven't used Yellow Cab for 6 months so when I saw a charge from Yellow Cab I thought I was fraudulently charged. I nearly closed my bank account due to their negligence, but I decided I'd call the company to discuss and resolve the charge. An employee named AHMED made light of the 6-month late charge to my account, talked over me, refused my request to speak to a supervisor and finally hung up on me. Yellow Cab has awful customer service and negligent business practices. I will not use or recommend Yellow Cab's service in the future.
