I bought a flight ticket from opodo. During the purchase, opodo asked me whether I want to try 15 days prime subscription. It said, I could cancel my membership anytime. I bought my ticket and accepted the prime subscription. After day 13 I wanted to cancel. Despite 90 minutes on the phone with different people, I didn't manage to cancel and was forced to pay the yearly subscription. They said they would send me a voucher. But I never received this voucher. I later booked a second flight (as I have the stupid subscrption anyway) and read very precisely: You get one free cancellation. I had to cancel and AGAIN that was a scum. I only got 30 % of my flight price and ONLY in terms of another voucher that can be used for another flight. THey are a bunch of criminals. I cut my losses but will contact my credit card issuer and dispute the transaction. Do NOT fall into that trap. Their reviews are cheated as well. The real reviews are all disgusted customers.
