Extremely sneaky and dirty company. We booked a flight through them, paid the premium amount for no-fee changes and cancellations when done before 24 hours of the flight. We requested a change of date 36 hours in advance, got notified that it was underway, then they apparently called the next day very early from an unknown number. Of course no one answered since everyone was asleep. We got a no-reply email saying that they tried to contact us. No number to call back, no email to write back, no information about what they needed. Just a generic message. Then we call the airline as we had no news from Opodo, turns out they hadn't made the change and said that we now had to pay an outrageous fee. An Opodo call center in India with very aggressive and useless operators finally answered the call, said sorry, we didn't answer the phone so they didn't make the change. No information, no request to contact them, no nothing, and of course no refund. Scammers if there ever was one. Stay far away from Opodo.
