Well, except they read the mail and, because it only mentioned the primary domain which their G Suite was anchored to that they had let lapse, and not the current domain which was subordinate to the old one, they decided to ignore it and deal with it “later” because they are a “busy startup” who apparently doesn't have time to deal with the fallout of switching business names and domains.

Pretty much what one Google CS rep said “you assumed this email wasn’t important, ignored it”
