Eskom Brackenfell Storage of Timber

I would like to launch a complaint regarding Eskom Brackenfell we are residing in a complex just opposite Eskom.They are using the yard for the storage of Timbers and treating them daily.The smell is very toxic and we are getting symtoms like nausea;headaches and dizziness.We contacted the Health department in Brackenfell but we have been struggling for 4months to get assistance from them.Its not acceptable for Eskom to store and treat these timbers in a residential area because it is very toxic when enhaled theres kids in this complex as well as pets that get exposed to it .Can you please urgently assist.
