incorrect email address linked to virgin media account

i signed up to virgin media back in November 2023 only to realise the representative who managed my sign up had given incorrect details for my email address which has left me without access to my account which is now building a debt i have no control over, as a single parent this is causing me and my little family much distress, the Wi-Fi gets disconnected every month without fail because the only way i can pay my bill is buy getting a text to say its overdue and getting disconnect for me to receive a link to pay the bill and this is also having a big effect on my credit score as its going down as missed payments. i cannot access my account change my details set up a direct debit i have tried to contact virgin media customer support on more than one occasion, ive wrote emails tried ringing i have even tried to contact the representative who was in charge of my account set up  but I've failed every time to actually make contact with someone from the support team. I think its also important to add how extremely difficult  it is to contact virgin media support team, i am Neurodivergent and every day tasks are not so easy for me, luckily i had help from a friend to use this platform otherwise id dread to think how long this would of been going on for.

I hope to hear back from some body soon to resolve this matter. 
kind regards,
