Need to close old virginmedia email that's being hacked
I had a virginmedia.com email that I could no longer access when I cancelled my old account and moved back in with parents a few years ago. I can no longer log in to the account online but it is still active on my iphone.
I have tried to change most things over to my current gmail account but have recently been getting password request changes for things I'd forgotten about like my EA account on Origin. There's other activity going on like emails not being sent properly and getting messages back.
I spoke to an advisor online about this but they couldn't help me as my old account was over 2 years ago. I just want this email account closed down. What can I do?
