Hi @Kkumari,
Welcome back to our forums and thank you for your post.
I am sorry to hear that you are having issues with your landline and apologies that your call was cut off. I can assure you this will not have been intentional.
I have managed to locate your account and have ran a few checks. Before I book a engineer out for you, are you able to confirm if you have tried a different handset at all?
Hope to hear from you soon.
