Logged another fault Ref No 253CRK26/01/16. Technician contacted me 12 Feb 2016. Replaced cable from pole to my house. Internet and line was working. Then had a call from a technician on the 26th Feb 2016 explaining that he replaced a cable running from a box. I informed him that the line was fixed on the 12th Feb. Getting home only to find that the line started getting intermittent and that there's a terrible noise on the voice side you can hardly hear the other person.
