Ring Setup

I have a question. My husband set up the Ring doorbell and an outdoor camera and I am the secondary user on the registry, but now he is not there and I need to set up the cameras with my username, but when I go to connect them, it tells me that they are already registered and that I have to wait 15 days for him to respond to the email that Ring sent him. I don't want to wait 15 days, and I tried to reset it to factory settings and it doesn't work. Does anyone know how I can fix it and be able to connect them to my username? Thanks a lot
