Hi there, I'm Fabien. I must say that my recent visit to the KLM Airlines Tehran Office was quite positive. The personnel were very personable, multilingual, and professional. They carefully answered all of my questions, helped me with my reservation quickly, and took care of all of my worries. The waiting period was comfortable because the office itself was orderly and provided a comfortable atmosphere. It was clear that the group was dedicated to providing top-notch customer service.
