Supertech Limited — Builder asking more money than agreed

Address: Gautam Buddh Nagar, Uttar Pradesh

Dear Sir/Ma'am I have booked a flat from Supertech at Noida ext-1(Eco- Village 1 flat No-A4-1205) in Mar 2010. They are making several changes in payment terms from the day of booking. Initial they said only 10% of amount is sufficient for booking the flat then they increased it to 15% just after the two months later I gave the 10 % booking amount. Due to local farmer dispute at the site and the matter was in court, the construction work could not made progress. Hence they modified the possession date to 31.03.2014 and made a new agreement letter on Nov 04-2012 and declared previous period as ZERO period. But at the same time they cleverly made us to sign on installment due dates since 2010(including ZERO period). Now at the time of possession after 8 months of due possession date they are charging interest on all installment payment made by us. They have shown our every payment as short payment, late payment and application for 24% interest chargeable. Total interest they are charging more than 1 Lac which is more than 10 % of the total cost of flat. Not only this, they are charging Farmer Agitation charges and Labor Welfare Charge which was never mentioned in agreement. They have not mentioned anywhere [protected]@5/Sq Ft per month for delay in possession in their demand letter which was made in agreement. I have attached all relative documents i.e agreement document, interest calculation document, possession cum demand letter document. Please suggest me, I have no idea how to deal. This please guide.
