I was on the 22:40 FlixBus from Edinburgh to London, picked up in Glasgow and scheduled to stop in Manchester at 2:40am. The bus broke down at Killington Lake Services.
They kept us updated and eventually a mechanic got it running again, but we arrived in Manchester around 5:30am, almost three hours late. Just after we set off again, we received a text saying we were entitled to up to £10 for food and drinks, but we had already resumed the journey by then.
The next day I submitted a complaint, but FlixBus replied saying the £10 food and drink credit was the compensation. I explained that we received the message after the issue had already been resolved on our end, but they responded with the same message again. I have now contacted them again and am waiting for another response.
