Dave Bater Cycles & Brompton mess up

This afternoon I excitedly phoned Dave Bater Cycles to check on the status of my A La Carte Brompton S-type, as when I ordered it on 19 September I was given an expected delivery date of the second week in December, 12 weeks later - a long time, but for something made-to-order a wait I was prepared for - in fact the timing would be perfect as it meant I could use the bike over my christmas holidays from uni.

However today I find Decemeber seems to have been put off until January, a 33% increase in the time from order to delivery. I am mightily annoyed, and feel I should be due some compensation for my dissapointment.
