Illegal Temple Structure on road

The key criteria of purchasing this plot & building our home was since this is a BDA Layout with 40ft wide road with ample parking space. Now there is illegal temple structure raised adjacent to my home on 19 dec 2023, which is just 3ft away of the main entrance. At the time of marking we raised our objection & complained it to local police station as well further escalated it to BDA engineer, BDA Commissioner, BDA superintendent of police. And after inspecting the site We were promised that the demolition would commence after election since police are busy scheduled on election duty. We even have a copy of letter which we received through Indian postal service, The construction was halted on (16 feb 2024) Now on 13.08.2024 the construction Resumed within 1day & 2nights The construction finished. Now again we visited the BDA office & explained the same they are saying now the construction is finished what can we do. All the dinning activities as well as parking of vehicles happens in front of my house. Now my tenants are saying they want to vacate since all of the parking space is occupied by these people. As well as they now started to threaten us for taking this issue through legal channels. Now what should I do any directions?
