Denied boarding for no reason
 

It's sad Qatar Airways to advertise all awards winning every year but their customer service to be so inadequate and rude. I was planning to fly from Athens to South Korea but Qatar airways denied boarding because according to them I didn't have correct documents to fly. When I contacted Korea immigration office and local Embassy they confirmed me that my documents were fine and Qatar wrongly denied boarding. I submitted complain claim to airlines website, attached all emails and documents I had from Korean government but still they refused my clam without any reason and valid documentation. Poor quality and low grade service.

If you were the only one, it was probably your fault. Somewhere along the line, you had to have skipped/forgotten something. Everyone else made it but you.

Have you talked with the Airport management after the incident?
