Brihanmumbai Electricity Supply & Transport Undertaking [Best] — Power outages since April 2022 on regular daily or alternate days

We live in Mumbai Null Bazar area. Building name Abba Building situated at 45 S.V.Patel Road, Mumbai - 400003. There has been continuous power outage from the month of April 2022 till date on a regular, daily or alternate basis. But the BEST Undertaking hasn't undertaken the work required to stop this issue. They themselves have confirmed that the Underground cables have been burnt & faulty & they are managing it in single cable instead of total 4. Due to this we the tenants of Abba Building have been facing power outages & even after complaining they everytime just change the fuse but don't undertake the required work of changing the cables & solving the issue permanently. This is causing a lot of damage to our Electrical Appliances too & disrupting our daily life & work. Kindly take strict action to see that the issue is resolved by working on grass root level.
