I stopped at a rest area in Texas on October 21, 2017 so I wouldn't have road noise to cancel a reservation for Weatherford, TX on October 21, 2017. After about 12 minutes I decided to get back on the road due to time restraints. A reservation agent answered after I waited for 14 minutes and 45 seconds and it was very difficult to make the cancellation due to road noise. A day or two before this date I had to make a reservation location change and also encountered a long wait time, but not as long as this one. It appears you don't have enough reservation agents working to care of your customers. I consider long await times to be unsatisfactory unless you notify the customer up front of the estimated time for long waits.
