Refund by MasterCard
I had four return tickets to Honolulu with Air Australia $2,790. The CBA Diamonds Awards have just refunded me the full amount, Not as a chargeback but as " Non delivery of goods " .
My travel insurance refused to pay because it doesn't cover airlines going broke.
The great thing is with the insurance there is a $200 excess. the CBA didn't charge anything.. so I am better off
normally I hate mastercard and their rip off fees but I am pretty happy at the moment
