Intermittent/No ADSL service

Logged a fault for intermittent adsl service on the 2nd December 2014, till today the issue is still persisting with no resolution. 30/01/2014 the Technician (Joseph) told me there's nothing he can do and that he would escalate to his supervisor and get back to me as my line needs to be moved. 02/02/2014 they sent a technician (David) who has nothing to do with my problem. 03/02/2014 I again had to call 10210 and hold for 35 mins to get feedback from Joseph to inform me that the issue will be sorted latest by 06/02/2014 as his supervisor has ordered the poles for my line to be moved. 05/02/2014 again I had to follow up and Joseph he told me he hasn't heard any feedback from his supervisor, when I asked for his supervisor contact I was told it wont help as he also wont do anything about it and that he will follow up on the 10th. 07/02/2015 I received a call informing me that the fault has been cleared and that all is in order, the issue is still persisting as I'm typing this. Could you please provide your client with a permanent solution as I'm still facing the same issue everyday since. Check my previous logged faults and for more info ask Joseph the so called Technician.
