I was a regular (every two days at least) user of Opodo with relatively few issues although it has become increasingly difficult to reach their customer support during the day. I continued with them but have now resolved to use Ebookers and Expedia after the most recent issue. Having booked a return flight to Point Noire in The Congo I called Opodo to change the flight to return a day earlier. I paid the £139 fee on top of the £1,800 air fare and was assured everything was in place. When my colleague arrived for his flight he was told that the flight had not been changed (Opodo had sent me an email showing it had been) but that his original flight for the following day had been cancelled, this leaving him in The Congo at 10PM with no fixed return flight. Calling the Opodo help desk was fruitless, it is only open between 9AM and 6PM so I instructed my colleague to return to his hotel. I called Opodo in the morning and they eventually apologised and re-instated his original flight. At the same time I emailed their customer services desk and have today (5 days later) received an email that says "thanks for contacting Opodo, please call our help desk to resolve this issue". The issue for me here isn't that they made a mistake, although it was significant, the issue is that when you need to call them out of hours, there is NOBODY and in today's 24 hour culture, and with a travel service, this is totally unacceptable.
