All I can get is callbacks for some places. This is newish. You can call, wait in the queue for 20+ minutes, get routed to voicemail, and leave an option for a callback. That’s it. And the CSRs won’t reveal any semi-secret info to confirm who they are, they just want info to confirm your identity. It is frustrating because “calling them first” for anything billing related has been my go-to for a decade.
