Kkay Homes possession: more hidden costs than I expected

Did a site visit to Kkay Homes in Greater Noida West back in 2021. They promised possession by late 2023, but we finally got it in March. Just moved in last month and honestly, the maintenance charges and some weird 'club membership fees' are way higher than what was shown in the brochure. Not sure if it's common for builders to do this. Did anyone else face similar surprises after getting possession for an under-construction project in Noida Extension?
