School giving transcripts Willy-Nilly?

I don’t even know what flair to use because this is an odd one. I lose my diploma, I reach out to the school I attended to get my transcript. They sent me mine, no issue. Right after that they basically offered me someone else’s too, said “we got another request for x persons transcript too, we believe that is you.” I said “NOPE IM Y THANK YOU” is this a normal thing? Where should I post this? Who can I reach out to tell?
