I am extremely disappointed with my experience with Opodo, and I am hesitant to renew my membership. I had planned to fly in 7 days and found a flight on Opodo. Due to previous issues, they provided me with a £70 voucher as a courtesy for my next flight. However, when I tried to use the voucher, the site crashed during payment, and now the voucher is showing as used. I have made numerous calls to Opodo (approximately 20 calls) and even submitted a written complaint to management, but I have yet to receive a reissued voucher. Meanwhile, the price of the flight has increased by £350. This situation has been ongoing for 3 days, and I am frustrated by the lack of resolution
