Hacked email help!

So a week ago today my email was hacked. All sorts of accounts being set up and actusl emails from the hackers telling my the pssswird I use. I have been frantically trying to change my important emails over to a gmail address. The email that was hacked is one I’ve had forever and it’s a blueyonder.co.uk which is an additional account according to my virgin media.

so I phoned for technical help, today I was told to create another email, I created a proton one. An email was sent to me but I was told it didn’t work, I then said I could try my iCloud one, it didn’t work either and was returned to sender. So the tech person said they could not help unless I made up another email address somewhere like gmail of which I’m not prepared to do as I’ve had so much bother this week already I don’t want an additional email. I was told nothing can be done then and the person hung up on me! They called back 5 mins later to say a ticket has been raised and I’d probably get a call tomorrow, I said I need it fixed today as I’m working tomorrow and I’m anxious about what’s happening. I said can you just delete the email account and was told no I need to sort this password to get back into my blueyonder email??? It’s a mess, I’m stressed, I’m not making an additional email so can somebody help me please to either get into this account to gather important information from my emails or to just delete it all?

thanks
