You are correct, I got my money back for now, but the chargeback is not finalized yet as far as I can see.
I do use Citibank Prestige, their highest current credit card and they are very accommodating.
My last experience with chargeback dates from a few months ago with Amazon, got a phone stuck at the Thai customs, asked for a chargeback, go the money, then Amazon confirmed they allowed the chargeback. Maybe I'll get an email from Thai once it is settled?
