Tried to call 4 or 5 times mid day only to have the computer ultimately tell me that they were too busy and to try back later.

Decided to try calling at 9:30 pm Pacific and got the option to have a call back around 2 hours later. It took 2 1/2 hours but I did receive a call at midnight.

And because I waited until they made an involuntary schedule change I’m getting a full refund (over 2K)

So wait if you can and don’t give up.
