I have bought 6 tickets from Alicante to Warsaw and made mistake in the date of flight (booked for June instead of July). I called them the same day with the request to change my booking with Wizz Air, which is normally should be with no additional charge and doesn't take a lot of time if you do it directly with the airline. Opodo agent told me that he had written request to the airline and I have to wait up to 72 hour for the outcome ( which I did not receive). Each time I called them each time I received the same answer(we made request, wait for 72 hours). It's been 11 days since I've been trying to resolve my issue with this company. I spent a lot of time hanging on my phone, it took me a lot of nerves to hear the same answer again and again with no outcome for such a simple request. This stressful experience is still going on. I am not sure if they will change the booking, if I can save my money, I can’t plan my journey. And yes, I also have prime membership which is completely useless in terms of customer support. It’s definitely better to book directly with the airline and avoid such a service.
