Welcome to the Community, sorry for the problems you're experiencing with your service at the moment.
To get caller display you'd need to add that to your account, you can do that by giving our team a call on 150 from any Virgin line or 0345 454 1111 from any other.
We'd love to hear how you get on and will be here should you need any assistance moving forward.
