Need to migrate email from a disconnected account

I have disconnected my COX services. I would like to access my email in-box in order to move some email and advise some people that my service has changed. I was told that I would have access to our email accounts for 60 days, but my wife and I are both locked out. What do I have to do to get this resolved? You will have to send replies to **** because I CAN'T access my **** account.
