Hi Scousediva,
Welcome to the Community and thank you for posting
I am very sorry to hear you are experiencing issues with your landline service, we will be able to assist further.
Before we proceed, can you please confirm the following?
Do you have a dial tone or is there no noise on the handset when you use it?
Have you checked all cables are secure and without damage?
Have you been able to test another handset to rule out an equipment fault?
Thank you,
Nat
