M&T Developments Units Infrastructure

I bought a unit in Fish eagle view. Three months after being occupied, The is water Leak which tripped the electricity and the Balcony light. I report after the 3 months of occupying the Unit. in September later year (2021) an electrician comes and Takes off the LED balcony light and says they will waterproof the upstairs balcony first in November 2021. It's December 2022 NOW and still no balcony lights or waterproofing. Every rain it gets worse. now both bedrooms are leaking. Trying to get out of this place as much as i can.
