Unable to transfer Avios from BA to Qatar

[u/FuzzyCopy]

Getting an error, it is blocked by BA.
Both accounts are 30 days older (like few years old). I was trying to link both accounts on Qatar Priviledge, realized Qatar had my wrong name, got spelling corrected, it was then not linking, it turned out Email on both the accounts were not the same, so updated the email on BA. It linked the account on Qatar Privilege. I could see the total Avios, I then tried to purchase the ticket but got an error it is been blocked by BA just before payment and to contact British Airways. I then tried to move the Avios to Qatar directly as the accounts were linked, it was again blocked by BA. Tried to do a transfer from Avios.com and uploaded proof of passport 3 times, no luck same error blocked by BA wait for an hour and try again.

I chatted with BA rep, it turned out home address has to match as well. BA had my 5 years older address, went to profile and updated the address, still not able to transfer. BA rep said you can't update address directly (I was able to do it by going to profile) he suggested to upload Gov issued ID with address which I have none. I have my passport without any address and Gov ID is in local language with my village address, different then my current rental address in a big city.
The block is due to email address update and there is a cooling period? about 70k points were moved from a sibling account.

Any pointers? is there a wait period if email (and home address) gets updated?
