I suspect BA will calculate the cost of an A class single SFO-LHR against the original ticket cost leaving a probably minuscule amount to refund.
OP will then have to somehow bypass the script readers and interns to get correct treatment.
I did think yesterday that BA deserved the trip in vain option. BA is unjustly penalising the OP with its incompetence.
