Squarespace Domain Transfer Error Puts My Domain at Risk

My existing domain on Google Domains was transferred to Squarespace, and now the previous owner is still listed as the domain owner. The former owner cannot access their email, and the domain is at risk. I am unable to reach Squarespace at all.
I urgently need a contact email address for Squarespace. My support requests have gone unanswered, and I am not receiving any replies.
