Hi Lorraine,
Thank you for your post, I'm sorry to hear you're having issues with your landline and have struggled to reach us. We can see from here that we're unable to make a connection to your landline service, so an engineer visit will be required. I'll pop you over a private message so I can help you further from there.
In future if you do need assistance with a fault, we're always more than happy to help you from here. You can also view our contact methods online here.
Thanks
Beth
