George. Thanks for coming on here to acknowledge the issue and to go some way to explaining the background to the error that led to the display of Christmas Day fares.
It's still a little unnerving to think that an advertiser will accept that a public claim to have checked the price of a product for sale would not actually have checked the prices of the actual fares offered for sale at all, and have hoped that that an explanation of a different process ("the way date suppressions are applied to our data feed") is a full and adequate explanation; but many other advertisers in a similar position will have remained silent or else hidden behind some corporate spin. So I, for one, congratulate you for the courage in reporting back on here, where there are so many vociferous critics of Railway Operators.
After all, we all make mistakes. Its our ability to acknowledge them and learn from them that marks our progress. You've convinced me that East Coast has done just that.
Thanks again!
