I faced this last year when waiting for a sofa that got delayed three times. Each update came by text, but no one confirmed when it would arrive. Eventually, I reached customer care using the contact page at
https://conns.pissedconsumer.com/customer-service.html and asked for local warehouse tracking. The staff apologized, scheduled a confirmed delivery time, and it arrived that weekend. They even checked in afterward to make sure everything was fine. Calling directly made it much smoother than endless messages online.
