Finally

after 5 emails since the beginning of this year, we received an email today that hubby has been upgraded to KF gold - but only till Dec 2020

I thought it would be when they actually did the upgrade. Anyway, better than nothing - hopefully the virus situation will subside and travel can resume to get some benefits from the KF gold. Maybe when hubby's KF gold expires I can do the Infinite Journey for myself (but not too eager, better stay with oneworld emerald)
For everyone who is still waiting for the upgrade, keep up the emails and fingers crossed. Good luck!
