Spring 2015 safety barrier outside my house collap...

Spring 2015 safety barrier outside my house collapsed I reported it and a temporary blue plastic barrier was erected. This fell down whenever the wind blew so sandbags were put up around it. 2 years later the temporary barrier is still in situ leaning against my hedge and overgrown with weeds etc. I have reported it many times over the last 2 years to the Council and the Parish Council but nothing has been done. My latest response from a Highways representative was that I had better sue the Council. Should I really do this and should I take on a Solicitor.
