If your experience is like mine, and you keep getting passed from agent to agent and they each want to start from the beginning, and you've wasted hours waiting/getting cut off, etc, having to keep repeating your story, receiving links that don't work, etc, etc---- There is a process for filing a dispute. You can go to this link: https://scache.vzw.com/content/dam/support/pdf/Notice_of_Dispute.pdf
