Hello,
It's me, again.
I contacted the airline, in this case Vietjet Air, to request an explanation as to why they denied me a boarding pass. Their response stated that I was denied due to being blacklisted by Thailand immigration, but they did not provide any proof. Of course I am dissatisfied with their response because, as I mentioned earlier, a reliable source informed me that I am not blacklisted.
Do you know where can I obtain official confirmation that I am not blacklisted by Thai Immigration? I have already sent an email to [saraban_imm@police.go.th](mailto:saraban_imm@police.go.th), but I have not received a reply.
If I have the confirmation, Vietjet is done!
Thank you.
