1 single transaction on the credit card.How much is your taxes? Did you see 2 separate transactions on ur bank app? If it was paid by credit card, then it should be 2 authorisations. Hopefully 1 gets cancelled.
They asking me to pay $910 perpax to make the changes but my old PNR was already $986p/p.
When I did a dummy booking with the same routing, the new total tax should be around $1k. So there is something wrong there.
