I tried and, as usual, SQ ground services failed. So I gave up and will eat whatever they have on board, as I spent/wasted lots of time on trying for previous flights and have never been (fully) successful.

It‘s a shame that they just don’t seem to get their other services to work, or don’t want codeshare passengers to be able to use them (for whatever weird reason), as SQ can be a real treat in the air. But adding a BtC meal to a fully paid F flight shouldn’t be too much to ask for and the cluelessness of SQ customer service means the airline is, in my book, not close to 5 stars at all.
