Renee Allen from Florida expected to be flying from Garden City, Kansas to Tampa via Dallas, she told Tampa’s FOX 13. But that wasn’t to be when American Airlines cancelled the flight because of weather delays.

Allen called the customer service phone number she received and waited for a response—a response that didn’t come until six hours later. “They gave me a phone number to call, I tried to call several times, only to be told that the call volume was too much, and to call back another time. And then it would hang up on me,” she FOX 13.

Allen added:

I thought maybe 30 minutes, maybe an hour and two hours into it, I realized this is crazy but I’m not going to give up. This really was horrible customer service. I just could not believe that I could not get through.

The woman ultimately hung up the phone when she couldn’t wait any longer, according to Consumerist.

American Airlines apologized in a statement:

We apologize for the frustrating experience. It was a very challenging weekend due to extreme winter weather impacting the Dallas/Fort Worth area. American had more than 2,000 weather-related cancellations systemwide on Saturday and Sunday.
