HACKED EMAIL Virgin unable to fix

My email got hacked. I changed all email details on virgin media systems, accounts and apps. Not once did I get confirmation of any sort. I raised a complaint and they said it’s been changed. I don’t get any emails except bills on my correct address. I RENEWED MY CONTRACT AND IT ALL WENT TO MY HACKED EMAIL ACCOUNT. I got confirmation in the page when I renewed and it said sent to (hacked email). I contacted Virgin my WhatsApp, webchat, email and phone and over 7 times for this to be fixed. Each time no one has a clue. No one speaks English and even when they do they keep saying the same thing. To change my email on the system. Now if I was that thick I would have done that. But I’m not. And I’ve changed it before even my dead mum would have told me. I’m fuming to another level because last week I phoned them and said change my email in your pathetic back systems. The guy didn’t have a clue and said it’s all showing as the one you want. THEY SAID THEY WILL resend the contract. Guess what. It got sent to the hacked email. How do I know? I managed to get in see some emails and the hacker managed to gain access again and locked me out. Now what does a person need to do to get virgin pathetic media to fix this. I can’t even leave as I just renewed. I don’t get why no one can help. It’s a SECURITY BREACH!!!!!
