Brihanmumbai Electricity Supply & Transport Undertaking [Best] — bus service

Today i. E. 24/09/2017 at plaza (Dadar) bus stop, i was waiting for bus no. 53, 85 or 354 from 6.00 pm to 7.00 pm for kurla east with my wife. But there was no single bus of this route in this hour. There is no notice board or instructions for this. Finally i hired a taxi. Is these bus routes are closed down. What is the reason? Who is the responsible person for this.
