Has anyone had success with a canceled flight, having the miles redeposited and then SQ forcing an open seat for a rebook? I would have left the ticket open (don't know if this would have yielded a different result) but the expiration was 31 March 2021, when I couldn't travel, and now it's extended through June 2021 when I can travel.
I had saver suites on SQ25 and they've shut off availability including waitlist.
Contacting SQ has been like butting my head in to the wall.
