Please DO NOT use Opodo Please DO NOT use Opodo. they are deliberately evasive and unhelpful. Our flights were with Thomas Cook and were cancelled - we received no message from Opodo to say this was the case. When I called to check if the flights were ok- I was told everything was ok. It was only when I mentioned that I was worried that they were cancelled I was told 'oh, yes thats right, your flights are now invalid- you need to rebook'. We are now trying to get a letter from Opodo to say that they will not be issuing a refund. We need a letter to try to claim back from our credit card company, but Opodo will not give us the letter. They say they are waiting to hear back from Thomas Cook. Asked to speak to a supervisor - told we have to wait 50 mins. Left exasperated and extremely disappointed.
