Pristine Builders — Complain about final flat finishing

Address:

Equilife homes, Mahalunge, 411045, Pune, Pune, Maharashtra

I own a flat of Pristine Builders at Equilife Homes, Mahalunge, Pune, 411045. I didnt get possession as per targeted date. So I moved to flat as soon as possible wherein they promosed to get work done related tiles routing for all rooms including washrooms. But its been 5 days I have moved noone is cooperating. And people given the contract are we don’t do this detailed work and raising voice for no reason, trying to convince that this is not our task to do. I tried asking sales people, but again the people given this contract are trying to ignore and hide under the hood. I really worried about this finishing work coz the flat doesnt look new at all. Please help me.
