Their customer service and service policies are shady and unclear. I was overcharged for a ticket change without a clear explanation of the additional costs and was cut off during my complaints with their phone support.
They refused multiple times (calls) to provide a transparent breakdown of the costs and once I even had to wait 1 hour to get through just to make a request which should have been available via other communication channels.
They also do not have any proper email feedback channel. They only reply via a no-reply email address to answer any queries, shutting down any further clarification of their answer and I have to reopen another chat to ask the same thing and provide a complete history of my request/inquiry.
It was the most frustrating experience I had with any travel so far!
