For weeks I have had a crackly phone line. Last week it got so bad my calls kept dropping out. Now I have absolutely no dial tone. I have run the usual tests and tried with another handset - tried every route possible to speak to a person and can't! Can't find an email address. Webchat is also too busy. Diagnostic tests have told me there is no identified fault on the line. I raised a query on here a few days ago - it seems to have disappeared.
