Why yours is taking so long I cannot imagine, as the process is automated.
FYI, if ticket refunds are done on BA.com, then yes, they are automated through the system, and should go through quite quickly. If they are done requested over the phone, it is not automated.
If Havent a Clue's refund was initiated via BA.com, and is still missing, then you are right, i would be worried as to why it was taking so long.
