I've booked a flight for 2 persons from Sofia to Vienna on 02.02 and return flight on 05.02. I've received an e-mail that the flight was cancelled and the return flight will be on 04.02 (instead of 05.02). This not suits me at all. I've called 5 times Opodo to ask for a resolution or refund if no flight on 5th is available. I was said that in case of refund, I'll need to pay additional 25 Euro per person. This is nonsense. I pay something that I haven't received, I've spend minimum 1 hour speaking with their hotline, in the meantime the tickets got more expensive, now I need to search for another airline company and for all this I need to pay 50 euro.
