I have no dial tone. I cannot fix the problem with the online suggestions & I am asked to ring the call centre but cannot get through as it is closed due to coronavirus. I cannot book an engineer online either. Very frustrating....I need my landline!
Thank you for the information, there would be a chance it's the handset but we've booked in the next available engineer appointment for you using the forum information.
Please check the details of this and reschedule if needed on your online account.
