Hello adishree
We're sorry to hear of the issues linking your Virgin Media account, we appreciate you taking the time to raise this with us via the forums and welcome to the community.
We have help here with a section specifically for VMO2 ID queries a little further down. One of the options is in regards to linking and advises the below:
When you register for a Virgin Media O2 ID, we’ll automatically link your accounts if your sign in email address matches. If you signed up for your Virgin Media O2 ID with an email address different to the one you used for My Virgin Media or My O2, we’ll ask for the details of your Virgin Media and O2 accounts and link them to your ID.
If you skipped this step during registration, follow these steps:
- Sign in with your Virgin Media O2 ID
- Go to Account settings, and then ID settings
- Tap Manage your products
- Navigate down and choose either Link your Virgin Media account or Link your O2 account
