Air Asia — no transit counter at dmk airport bangkok

I travelled from chennai to ho chi minh, vietnam through bangkok on 10th dec 2017 10pm.

My tickets were booked with two legs in two bookings and transit time is 3 hours.

In chennai, i got only one boarding pass and was told to collect at transit counter when i asked for the second boarding pass.

When i reached bangkok, to my surprise, there is no transit counter that can issue boarding passes in bangkok and only one staff with a transit desk just to verify the documents and allow to proceed to transit gate.

Since i didn't have the second boarding pass, i was not allowed to go through.
I was told to get on-arrival visa, clear immigration, go-to departure hall, collect boarding pass, clear immigration & security, go-to the gate.

After hearing this, i was under lot mental pressure as i can't afford to miss the second flight which is in the next 3 hours.

I requested the transit staff help to just ask her colleague in the departure hall counter to issue me an e-boarding pass or something similar as i already done a web check-in for second flight and i don't have any check-in baggage to collect.

But the staff is in not a good mood and insisting me airasia is budget airline and i should follow the rules of airasia.

I had to spend rs.8000 additionally for the on-arrival visas just to collect boarding passes (Two times since return also same thing happened) and my total flight costs wentup to rs.33000 for chennai to vietnam return trip in a so called budget trip.

I heard airasia is providing one transit counter in klia2 to issue boarding passes, but not in dmk bangkok.

I want to bring this up to airasia management that their staff can be little more helpful in such cases (They can even charge me nominally rather than me spending 8k and mental pressure) and make arrangements for transit counter in dmk bangkok.

Otherwise their marketing of "air asia fly-through service - fly conveniently & hassle-free" is just going to be another wasted effort, time and cost.
