Supertech Limited — Gross mistake in calculation of Interest charges and non payment of delayed possession penalty

I had bought a flat in Supertech Capetown, Sector 74 Noida in 2010 (CG1 - 1104). The payment plan was of Construction Linked Plan in which it is clearly mentioned that the payment due dates would be based on the construction progress. Recently, i got offer of possesion letter from Supertech in which following gross fudging of data was found while calculating due payment from me - 1) I have been shown to have made delayed payments. The payment due dates taken by Supertech are those which they had mentioned in Allotment letter and not as per the actual construction progress. Hence, they have shown that i need to pay a delayed payment interest of approx. Rs. 80000.00 to Supertech. 2) On above pretext of delayed payment from my side, Supertech has clearly refused that they would not be paying any delayed possession interest to me. 3) I had been made to pay 100% labour welfare charges which have to be borne by Supertech and the flat allottee in ratio of 50-50%. When i asked Supertech to credit my 50% of share of welfare labour charges that i had initially paid, it has clearly refused me. Pl help me to get the above issues resolved. I am also planning to take legal action as i have got good evidence along with payment demand letter in which dates are different. What a way of fudging the figures that these builders have resorted to!! There should be some strict rules against big builders otherwise they would keep on playing with innocent customers.
