Welcome to the Community, I'm really sorry to learn about the problems you're experiencing with your phone line at the moment.
I've been able to locate your account and take a good look at this fro our end for you. There are no reported problems in your local area at the moment and your individual line is looking good.
Have you been able to test your handset at all? By trying your handset on an alternate line or an alternate handset on your line? Are the incoming calls coming from different phone lines/numbers or just one?
I'd like to arrange for an engineer to come and take a closer look if you're available. I've sent you information regarding this in a private message, which you can view by clicking the purple envelope on the top right of this page.
