Once in a lifetime experience ruined

What is soon to be a once in a lifetime experience for myself and my best friend is now turning into a bad experience. We decided to go to the UK and do the Trafalgar 12 day Britain and Ireland experience.<br> <br> We trusted that using a reputable travel agent such as Flight Centre would ensure that everything would go smoothly on the travel arrangements. From getting on the plane in Joburg to joining up with our tour group in the UK.<br> <br> This apparently is not going to happen, as the agent responsible for the booking advised us to take a flight which now arrives in London after our Tour group has departed. <br> <br> The branch manager Liesl has been trying to resolve the error, but her solution is to take a train to Cardiff, missing out on the entire first day of an expensive tour.<br> <br> This is the worst experience that I have had in my life - you would at least think that Flight centre would ensure that we get in London in time for the start of our tour. <br> <br> I am utterly disgusted and to find this out 2 weeks before we leave - utter negligence on the part of the agent, who doesn't return our calls - if I hadn't decided to escalate to the branch manager - I would only have found out in London.
