Bereavement transfer

Hello, my dad passed away in May. I have filled out a transfer form to transfer the Virgin Media account into my mum's name. The TV, landline and broadband package will remain the same, to the same home address, same email address and same bank account (but now in my mum's name). Today, I've had an email but I don't understand. It mentions my dad's contract ends in August 2026 and he was paying £76 per month, but not to worry as Virgin will apply a £45 discount for 15 months. But she will be billed £76 a month for the new account being in her name. Does this mean she will be paying two contracts simultaneously? £31 a month for dad's and £76 a month for herself. I think that's shocking if that's the case because of a bereavement.
