I have bought a commercial shop in 2019 with a builder project in Gurgaon. The builder was charging 12% GST on every installments. I came to know that Customer shall be entitled to get ITC benefit and lot of judgments have been passed by NAA for anti-profiteering. Now when I encountered the same to builder, they are saying that I'm not entitled to get any benefit as they are paying 12% to Govt. This is the same builder against whom Order was Passed in Dec,2020 for anti-profiteering for a different project in Gurgaon.
Pls guide how should I proceed further? what documents I should ask them?
