Unable to link VM / O2 Accounts

Like many others, this is my last resort.

I'm a returning customer (Well over five years since I've dealt with Virgin media, now I remember why I switched in the first place...) Eager to get on and change preferences such as eBlilling, however, despite multiple days & countless attempts..

I've attempted changing my email address so many times, I've created burner emails. Etc etc. Nothing has worked, every single swapped email has been triple checked

I'm also using the account number provided by the first bill I've received as well as the area code..

Supposedly, according to the top moderation post, this issue has been fixed, but clearly that isn't the case, or they have an email address on file that I haven't touched since I left the service many years ago.

Can I please get this resolved as a matter of urgency, over a week now I've tried to resolve this myself & none of the information through any platform (Including the forums themselves.) Have been any help.
