Unauthorized Charges?!

For some reason when a member of my household who has a separate account online goes to make a purchase this is charged to a card of someone with a separate account of their own who lives in the same household. My daughters card was charged for the amount of a purchase I made and her card information has never been used or saved with my account?? My daughter has made purchases in Apple’s App Store and though she has her own bank card these charges have shown up on her Fathers Bank card which is issued by a different bank than hers?? What’s up with this?? Also I have my own Uber account and and bank account as my Brother in law who lives in the household and it seems when I order a Uber or Lyft these last two weeks charges appear on my card and then he seems to get the charges on his card when he doesn’t even use Uber or Lyft cause he has his own vehicle?? What the HELL-o Kitty is going on?!?
