Registry nightmare through this app

Does anyone know how to delete my registry on here? I keep getting these stupid “gifts” for Amazon gift cards for a couple dollars from people multiple times a day. It’s excessive now. I tried to delete my account completely and STILL am getting them so I just reactivated it to try and figure out how to stop this. Anyone else going through this or know how to permanently delete the registry or account?! On the emails there’s a button that says “unsubscribe from emails” but when I click on it it says the links “not found”. I wish I had never made a registry and can’t wait to get off this app.
