I was going to ask this to an agent in the Windows section, but they denied my access for ...

asking for a supervisor is not going to help you, they have the same tools that the agents do, many a supervisor has told me this in fact supervisors started denying my calls untill i allowed the agent to attempt to help me -.- so no don't ask for a sup

is down and cannot access my account!
