Disgusting behavior and lies!

Absolutely HORRIBLE!!! The agent just HANGS UP on you when you are trying to get the explanation from them. Because of Covid, the airline cancelled the flight. After speaking with multiple agents, it was clear that the best option was to keep the ticket open, schedule nothing and just wait until the airlines start flying again. Then, i would pay 30 euros to get a new ticket as it's considered "involuntary change". However, if I took a voucher then in March to exchange it later for another ticket any time for the next 2 years, i would pay 50 years. I chose to wait, called today to get a ticket and guess what - they want me to pay 30. What on earth?? After i asked the agent to explain me what she thinks "involuntary change" is, she just hung up on me lol What looser does that? Is that customer service? That's a disgusting behavior both as a human and a customer service rep. You should choose your agents better. That's unacceptable!
