Email access gone

I have an NTLWORLD.COM email address. I have had it for 25+ years. 2 months ago i lost access to it. I have all sorts of accounts tied to this account. I am missing important hospital correspondence and lost access to tickets for events etc. I have made 9 phone calls to virgin (an absolue nightmare each time) and been messed around horribly. I have been told temporary technical fault. IT are looking at it. 2 months and no one can sort it.

I raised a complaint. They said they tried to contact me to resolve it (they didnt try to contact me). They say this every time i reply to the complaint but not a single phone call or missed call. We tried to contact you. Heres a solution, reset your password. This is not a solution. I cannot reset my password. Virgin have reset my password but i cannot access any page to log in.

"Customer support" got me to create a new virgin account under a gmail address. They then linked the old email address to the new account. When i click on virgin mail i get a "Page cannot be found" error. The address of the page it cannot find has "invalid credentials" in the link.

Under my VMO2 settings, if i click "manage my products", i get a "Something went wrong page"

Are they just trying to get me to go away and not have to deal with email any more? No one is addressing it. 9 calls and a complaint, several times being told i will be contacted by tect support but nothing is happening. No one is contacting me. People on complaints dont seem to care though they did offer me a £10 refund. Cheers that will make up for 2 months and counting of no email and lost tickets and who knows what important emails ive missed.
