Terrible Customer Service

What a terrible experience!! Booked a flight for 2 passengers through the web site, then later on received a message that the time of departure of the flight has changed. So then contacted them through the chat. After asking for new confirmation documents for the new departure time, the agent said "Hi" and then it went quiet for about 5 - 7 minutes, without responding. Only when I asked if the chat was still active, did the agent say that he is busy. Turns out that only one of the two passengers was put on a different flight. So the passengers on the booking was split to two different flights. So I phoned them. You can hardly hear the answering service and it sounds like they recorded the message in a construction site. Eventually got through to an agent. That was totally useless, since the agent could hardly speak English and I could not understand a word she was saying. Then I was put on hold and the call got disconnected. So I phoned again. Got through to a different agent, but had the same problem. This agent also could not pronounce the words correctly and I could not understand a word he was saying. I called again, were put on hold during the conversation and then disconnected. I called 6 more times and each time the call was put on hold and then disconnected. Every aspect of the service I received was unprofessional and frustrating. Don't think that they even deserve a full star!
