I am trying to book a flight and I keep getting this error when they process my payment "This transaction is not approved by the issuing bank."
1. I tried multiple types of cards from 3 banks I am with. Visa and MasterCard, Debit and Credit.
2. I called each bank all confirmed one thing, the transaction doesn't even reach the bank.
3. I tried the Chat they told me by default message, without checking to try another card and talk to the bank, and ended the chat.
4. I tried other browsers, no luck.

My guess their payment processing service is at fault.

Has anyone had the same issue? Any solutions?
