Minecraft dungeons automatically bought!

at 2:30 pm i got a message from my bank account that says that i bought something from the microsoft store which i wasn't using the laptop at that time, when i opened my laptop and clicked the windows start button i found "minecraft dungeons  recently added" yet i didn't buy that game, i just went to my files and found minecraft dungeons file with it's date being today 2:32 pm (basically 2 minutes after the purchase). the same thing happened with minecraft legends 2 days ago but i let it slide and tried the game because i didn't know it was the same case as minecraft dungeons and though it was a gift instead! please return my money for the dungeons game, and thanks.
