Slow service to repair ADSL/telephone line

Since August 2013 we have waited for Telkom to replace a corroded connection box without a cover on a telephone pole for our lines! As soon as rain arrives our line is noisy and our ADSL connection is intermittent. Every time a Telkom technician comes out it is a temporary repair and promises to report the need to replace the connection box to the relevant department. This has happened again in February 2014, August 2014 and May 2015...still no replacement of the box. Now we are told new wire must also be run from the pole to our house because it has no more insulation on it? Again this must be reported to another Telkom department within Telkom? I don't care which Telkom department must fix the problem, I only deal with one Telkom, so Telkom please sort this problem out once and for all!!! :-(
