Did your PA book on ba.com?
If so, you need to get a PA who is more attentive to detail. It is not possible to make a booking on ba.com without being shown a page of fare conditions which makes clear that there are no changes and no refunds.
FWIW, the receipt you've posted suggests that (if you're booked London-Washington-London) you have an I class fare in one direction and an R class fare in the other direction. If it helps, the R class fare is changeable (for a change fee of £200 plus any fare difference), so that half of the ticket should be changeable even if the I class half of the ticket is not.
