Hi @Gagong,
Welcome back to our Community Forums! Thank you for your post, and I'm sorry to hear that you're having some issues locating your Virgin Media cable.
Have you had a look around the external walls of your property to look for a Virgin Media box as @stabilo00 suggested? Have you been able to connect your equipment, or do you require further help?
Please let me know. This way, if needed, we can arrange to have a technician come over to take a look this is for you.
Keep us updated if you can.
Thanks! 🙂
