I booked return ticket with Opodo from London to Vilnius, flighing on 12/03 and returning on 14/03. Checked the dates 3 times (as I always do) and clicked thr "pay" button. Couple of minutes later received the confirmation from Opodo with return date on 04/04. Their customer service must be receiving complaints about the wrong flight dates all the time because when I called them they said (of course) it was my fault, I must have selected the wrong dates, yet offered refund straight away.
Reading google reviews later I realised how extremely lucky I was. Other travellers who had the same issues with Opodo only realised that they had the wrong dates in Opodo confirmation email when they tried to check in. By that time it was too late and Opodo would refuse any refund.
Don't think I will ever try my luck with Opodo again!
