Noise pollution in residential area

Gothic Construction, think it is acceptable to continue construction right next to a residential complex in Fourways until 4AM!!! After complaining multiple times they stopped for two weeks and now they have reverted to stopping at acceptable times but then they start construction again at 3AM!! This is a blatant disregard for the individuals at Shingara Sands and their health and overall well-being. The noise pollution is completely unbearable!
