I just wanted to throw my hat in the ring with the refund/phone CM situation. I'm sorry if anything like this was already covered, but I figured it would help someone.
I called today to ask for a refund rather than the extension. I have (had?

) a platinum AP. I paid $808.34 for my pass (it was an upgrade completed in March 2019).
My pass expired May 17th, so I have 64 days that I will be refunded for.
I asked if the refund would be prorated for the amount of day the parks is closed - yes.
I asked if it would include tax, or be the before tax price - she said no one has asked her that question before, but she said the language they received was "refund for the cost charged", so I'm taking that as post-tax.
So this would be:
($808.34/365) x 64 = $141.74 refund
I asked how the refund would be delivered. She said it would be issued back to method of payment. I asked her what would happen if we didn't have that method anymore. She said the following:
Disney will send an email out prior to issuing the refund saying "a refund of x dollars will be issued to x method of payment". At that point we can reach out dispute the method of payment and request a gift card, check, or electronic transfer to a banking account etc. She also said that Disney will attempt to refund to the method. If it's returned, they will reach out to us to let us know that the refund was rejected by the institute and we can choose the refund method.
