no adsl for almost a month

I reported a fault on 8 january 2015 and called the call centre 12 times and only got resolved after 3 weeks. On 28 january 2015 adsl line stopped workinng again and reported another fault. Still not resolved. Takes 2-2 1/2 hours to get through to a consultant and when you eventually get through,consultants are rude and patronising!!!! Pathetic service and I still get billed for the adsl line depsite not being able to use it!!
