Searching for "Mastercard Priceless Leak" from 2019

[germane]

hello,
I need the Mastercard Priceless Leak from 2019.
(the files were published as: kundenliste.csv and mc.txt)
Inside is an old cc from me (which is expired and card is already destroyed)
but my Microsoft Account was hacked, and now I need this old creditcard
to prove it is my MS Account.
Microsoft just needs the last 4 digits.
so if someone has this german mastercard leak
