Consumer Redressal

Dear Sir/ Ma\'am, We purchased a flat in Kolkata from builder Bengal Shrachi in their project Greenwood Nest Project in te year 2010. Since then we made payment of total over Rs 15 lakhs but the project got stopped due to some reasons not disclosed properly to us by the builder. We filed a request for cancellation in early 2014 and requested for a refund as per their policy mentioned in contract. They were supposed to refund in 60 days but it has been 8 months but no refund till now neither they have the courtesy to reply to mails or phone calls. We have all written evidence of mail communications and reminders sent by us and fund transferred to them in several installments. Kindly take up our case urgently and guide us how we can recover our money along with interest (they promised on interest payment too) as soon as possible.
