Security parts not connecting, unable to reach Ring Support

I bought a house, and the previous owners sold me their Ring doorbell and security system. I got the doorbell connected, and I’ve got the alarm base station connected, but I can’t get any of the other security parts to connect. At first, they displayed with the message, “Waiting to connect to a network.” I followed posts in here that said to remove the items from the alarm base, and then you’re supposed to be able to get the items to reconnect. I removed them, but no matter what I do, I can’t get them to display. I’ve attempted to contact Ring US support six different times, and the call consistently disconnects after I press 1 for English. I tried to do a support chat, but I received an automated response saying I needed to call the support line. I need help, please!!
