This worked really well for me. It was Sunday night and instead of holding for 10 minutes, Fast Customer held for me then connected me with an agent. Note: Answer your phone quickly, as the first agent hung up on Fast Customer.
Got a call back from Jerry at United Airlines within two minutes. Got my refund in 8 minutes. Great service from fast customer and from United.
Waited 2 hours on hold and gave up. Now I'm using this service and have been waiting for 2 hours with 2 different phone lines. United Airlines loves to waste their costumer's time.
I've been on hold to United 3 times today. Each time took over one hour. And each time I was cut offin the middle of a simple transaction and had to start again!!!
