Strange, I've always had a reply within 24 hours from supporter.services@bhafc.co.uk . Have you tried contacting the transport manager, Steve Reeves (Steve.Reeves@bhafc.co.uk), again, he's been helpful to me in the no so distan past via email.
The announcement is any time now, the franchise takeover will be in September and the merger between what we know as Southern and FCC is due next Spring/Summer. Frankly I won't be holding my breath that it will happen on time. MTR are also very confident of winning it, but I guess none of them...
They should be, the announcement of the tendering process should be quite soon. I think there is a lot of expectation that the firm that will win it are from China, so goodness knows where the new call centres will be.
