Yes, AirAsia is near impossible to get a live person, unless you go in person. I have also tried to cancel a booking. Not gonna happen. Change, sure. For a fee of course. Cancel... I don't even think that option is available on their website or app.
Honestly, it depends on a lot. If you are travelling now, you are stuck with it. If you are not traveling, I would get a new one as soon as possible. Some countries will give more leeway than others. Make sure you have your driver's license with you.
You could get the multi entry visa to start with. That would give you 6 to 9 months of no worries. You WOULD need to leave Thailand at least 2 times. Maybe that will give you enough time to figure out a better option. You technically can't work on any tourist visa (including Elite).
