Angel S Packs optima Packs - Factory making wooden packaging materials in residential area

A factory making wooden packaging materials has been operating in our residential area since more than a year. Lot of cutting & industrial drillers are being used to make the wooden packing materials. Due to this there is always wood dust, which is causing health issue to us as well as our neighbors. We are forced to keep our windows & doors closed due to this. Sometimes they operate until night. Even after repeated complains to the owner of the land & the factory owner they don't seem to be going for a relocation.
