Unrecognizable email can't log in

I have a WD MyCloud and I cant access my account. None of the email addresses I might have used are recognizable. How do I retrieve my initial set up info? I have important images on the wd cloud

@speeditup Are you able to open up the Dashboard? More information about what is happening would help. Are any messages popping up when you try to log in?

Can’t see anything , there are several issues one being my mac pro that I initially set the cloud up on, was hacked to the point of no return However my other device was synced and I need the info backed up on my cloud, the second may be I moved, I was on the phone with WD support for hours, all I accomplished was hours of tech issues with apple and my cable co. still can’t retrieve account info from wd sent an email still waiting. Any suggestions ?
