Probably best to email me again and can look at checkers and do the prodding once again, suspect a manual change was put in place, but has been overridden by an automatic update of data.
On the broadband offers, some of their deals are only available to online orders, so would need to know details of the offer and might try prodding that side of things too, i.e. need to be very clear about what the deal you want is such that order goes through as soon as checker is good.
In theory those in the backroom at BT Retail (and other providers) should be able to do this sort of prodding, but getting to those people is the difficult part.
