If you have a V6 box you can try to update your channels by using your remote and clicking on
Home > Help & Settings > Help > TV Care > I'm missing some channels and allowing around 10 minutes or so to update.
Otherwise yes try rebooting your VM TV set top box.
Thanks for coming back to us on this one. I'm glad your dad has been able to check this and let you know.
As this is your dad's account, we would like to look in to this further but we will need to confirm his details. I have sent you a direct message to allow us to do this with you in a private space. Just click on the little envelope at the top right-hand side of the page to access your inbox.
Thanks for taking the time to come back to me via private message. I'm happy to hear that things are now resolved for you and your father.
If you have any further issues, pop back and let us know so we can help further.
