Excess Baggage Fee Flying Air Asia

[Aland]

I'll be flying Air Asia next month from DMK up northeast Thailand. When I purchased my ticket I opted for 40 kilos checked luggage as that was the highest option. After purchase they advise that one purchases for excess baggage online or through the app. Both options offer up to 60 kilos BUT when I try to upgrade, it never goes through and of course there is zero customer service available other then "chatting with A.I. Bo". Does anyone know what Air Asia is charging per kilo for excess baggage or know of anyway of contacting customer service to enquirer about repurchasing excess baggage?

40 kilos of luggage?  That's a lot of meth.
