Hard time booking for family with avios
I have some 100k points locked up in Avios, which I transferred from a credit card into BA-Avios at some point. I had made a household account, adding my spouse and 2 kids. After not logging into kids accounts for a couple of years, I realized they have been locked out. All attempts to recover them failed because customer support always asked for last transaction for verification, which I can't remember. I've tried correlating to my account transaction but nothing worked. I've called several support options, like avios club number, chat support etc., all ended with the same result.
To make it worse, I was no longer able to transfer those points to Qatar, and this always failed without any explanation why. Suspecting this could be due to these locked kids accounts, I deleted them off my household list and was able to transfer successfully.
Now, when I try booking through Qatar with Avios, it tells me I am restricted to only those in my family list. Visiting my dashboard on qatar > Profile > Friends & Family, I see that this does not have anyone (probably a separate list from BA-Avios household, which still has my spouse). And I see this - without an option to add anyone new -
"You can start adding members after you’ve been a Privilege Club member for 30 days and have collected Avios by flying or using one of our co-branded payment cards."
I have had my Qatar login for much longer than the 30 days. I also flew their flight recently, although I routed my earned points to Alaska airlines. I don't have their credit card.
What is my option to use these points to book for people not on this list?
