REMOVE OR BYPASS ICLOUD ACTIVATION

REMOVE OR BYPASS ICLOUD ACTIVATION =WHAT ARE MY OPTIONS = I PURCHASED A IPHONE X SECOND HAND FROM A NONPROFIT CAMPAIN ORGANIZATION. THE OWNER ERASED HIS INFO BY RESTORING THE PHONE BUT DID NOT UNATASH THE ICLOUD ACCT. NOW DOES APPLE OFFER ANY SUPPORT IN THIS CASE,ARE WE JUST LEFT OUT IN THE COLD TO THE DOGS THAT CHARGE TO GET THEM UNLOCKED. THAT ARE VERY SHADY IN MY THINKING.
