OK, that's a lot clearer. So that distance and circumstance puts you into the 75% league for EC261 downgrade refunds, and yes the carrier surcharge should be refunded at 75% too. The Mennens case should give you the EC261 formula, BA also has internal "involuntary refund" calculation which sometimes is more generous than EC261 but if I were to speculate here (without knowing the precise amounts) then it's likely to be a 50-50 call as to which is the more generous. I presume you specifically asked for the EC261 refund on the ticket?
So what I would do while waiting - and yes this does take a ridiculous amount of time - is to calculate quite precisely what the EC261 amount should be, then when BA have completed the refund process you can work out if you were diddled or not.
