UKVI decision letter missing

hi all , I applied for dependent visa for my daughter along with my family . We thankfully got our passports with the vignette stickers but the UKVI decision letter for my daughter was not attached . Any idea whom I should contact to get a copy of that ? The other members of my family got it so I think it might have been an oversight when sending me the passports back
Any help appreciated

Hi,Pls how did you resolve the situation cause I have similar omission.

Same issue with my daughter… we are flying anyway… any inputs?
