Hi @mac51
Welcome back to the community forums.
I'm really sorry to hear that you have not received the support and assistance regarding your home phone switch over.
Customers require to have a Hub 3 or above, so either a Hub 3, 4 or 5 for the fibre home migration to be completed, and work in the home. I have checked the systems at our side and can see that you do need a Hub upgrade for your migration and can see that this has been arranged for you prior to when you state your letter was received, My apologies for any confusion caused by this.
Please do let me know if you are unaware of your appointment time and date or any details for this and we can bring you into private messages to pass account security and confirm any details for you.
