Hi @JonReese,
Welcome back to our community forums and sorry for the confusion with your first bill.
We want to best help regarding this. We typically bill you for 2 months for your first bill, this is done because we bill in advance. You can find out more here https://www.virginmedia.com/help/virgin-media-first-bill.
In the case of your package, your package cost is £51 however due to a new customer discount, your monthly rate is
£23.95.
It appears there has been a £100 credit applied to your account so deducting your first bill, you currently have a £52 credit on your account.
Does this make sense?
Do you need any further help with this?
Thanks,
