Worst Airline ever!!! Never flying Qatar again! ****med with 220 USD

Cancelled a flight within 24hrs of booking thereafter no cancellation fee. Took a travel voucher instead of a refund. Only to find out that a travel voucher and avios can’t be combined. They **** you into paying 220 USD to refund the travel voucher back into my account for myself and husband!!! ****mers!!! It’s so disgusting ! I’m so disappointed I’ve built my tier to a silver member but clearly they are just greedy animals trying to make money anywhere they can. I’m done with Qatar airways!!!
