Noise level concerns

To the staff working at 108 Albert Rd, Woodstock, Cape Town, Please be considerate when you leave your office at midnight and early hours of the morning. The noise levels of the staff is unimaginable and very unprofessional. Telus staff do you realise that there are people living in Frere Street? Every night our sleep is disturbed by the staff shouting, screaming, cars / taxis hooting when they leave office. Please be considerate of others living in the area. I complained about this 3 months ago on their website and no response recieved. the staff unruly behavior is getting worse
