In my case, when I cancelled two reservations, one of the companion codes got put back in about a week, for the second one I had to call/msg after 10 days they seemed to have forgotten about it. No issues after the reminder though

Please let us know if your reissued code does have Feb 2021 expiration or much further out, since at the very least this seems like a way to extend expiration by a few extra weeks for those who's code is expiring at end of this year.
