What is wrong here?

I have struggled for just short of two years with Telkom/Open Serve to complete the fibre installation in my complex in Waterfall, Durban. Three complexes in the area had some fibre laid four years ago mine being one. In each case the contractor did not complete the work. Every attempt to have Open Serve complete the work falls on deaf ears, I have supp**** them with photographic evidence detailing the problem. They have inspected the site I live in, but no action to date. I have contact details of some of those contacted. In the past week, somebody nearby who hasn’t app**** for fibre had their place ‘fibred’, yet our three complexes receive no support, we want to know why?? I want action! What is the highest level contact you can supply me with as obviously something is very wrong? Some of us are on ADSL and Telkom informs us they are going to stop the service, yet will not give us fibre? Please respond urgently with a solution to the problem. Thanks
