AA COVID cancelled flight from Joburg to Toronto in 2020 but told me "don't worry your credit is safe". Cost my wife and I >15000 to return home on SAA and AC 2 months later. My safe credit turned out to be a fiction. AA Customer Relations extended credit 2X because of COVID .... good. However, when I tried to use it "Booking" said no credit existed and it had expired even though it showed in AA Advantage membership. "Booking" than told me credit was only good for same leg of flight from SA to Canada. I booked elsewhere but contacted Customer Relations for a refund showing available in my AA Advantage of $1900+ each. Customer Relations sent me to "Refunds" to handle. 'Refunds" told me that refunds only given within 1 year of cancellation. They didn't mention this at any time when they cancelled flights or in any of many correspondence since. Does right hand know what left hand is doing or is this deliberate policy to defraud customers? Never will fly AA again.
