Got to agree with twitter being a good place for customer service. I've had two shining examples. One was from Dales & District who I queried some fares with and they replied to me almost instantly, and even advised of their "Explorer" ticket. Another one is the Megabus account, who whilst on a day out in Newcastle, I wanted to know whether a specific coach was due into Newcastle (54206 I think it was, the Young Scot Awards liveried one) - the twitter team checked with control for me and had an answer within about 15 minutes. I thought that was really good of them. They even asked me to tweet the photo that I got and then retweeted it to their followers!
