Builder charge GST for sale without invoice - Goods and Services Tax - GST

Hi Team, I booked one plot from the reputed builder in Chennai. I paid almost 90% of the sale consideration value including GST as mentioned in the builder quote. When i asked for the GST invoice, builder gave only receipt without invoice and GST number. He say GST bill will not be provided. is this correct? in the quote, Builder mentioned there will not be any rebate of GST input credit to be pased , Being individual, Am I elligible to claim input credit? thanks, Velayutham
