Feature shown in brochure for flat, but not provided by buil

HI 

You can sue the builder in the consumer court. 

The rationale is that the brochure is an offer based on which you purchased the flat. 

moreover, disclaimers in offer document which are arbitrary (in your case builder refusing to provide amenities) are always void in eyes of law. In your case, the builder should have had your consent in case he does not want to install the equipment, which if did not happen, is bad in eye of law. 

Builder give a Brochure for only for knowledge for that u read last line of Brochure or if u make any agreement with Builder they write one pera that Brochure is not velid because it's give only for your knowledge we can do some changes as per our requirement in feture.
