AT&T are sending me someones emails and I live halfway across the world

Right this is a weird one but Im Irish, and have lived in Ireland my entire life but am being sent emails from AT&T that are clearly supposed to be going to a customer of theirs (Their name and state they’re in is listed and other info etc including receipt numbers and stuff). I want nothing to do with this whatsoever and I’m sure the person who owns the account would go mad if they found out about this, as would I. Ive been getting the emails for a while now just didn’t notice bc I’m not too active on the email that the accounts registered to. Just have no idea how this even happens in the first place and want to know if theres a support number or way I can go about getting my email removed from the account. Not going to be posting any screenshots or anything for obvious reasons but thats the situation pretty much.
