I booked flat in TGS Newyork in year 2015 and paid 6 lacs rupees when dint get any clue of construction start I followed up by going to their offices in HSR layouts and got to know fake stories and cancelled my booking after almost 6 months or so. they gave 3 cheques worth 2 lacs each with a date post 72 days. when i deposited the cheques they got bounced. DreamzGK, TGS Gruhakalyan all are same with Sachin Naik as owner and the case is with CID all knows about it but they are not giving any refund. How to get our hard earned money back?
