Nobroker — Refund not processed

I had taken “Super MoneyBack” plan from Nobroker for one of my apartments in Thane for a cost of Rs. 11, 798.82 on 10th Oct. I however, finalised the tenant through another source, so I seeked the refund from the NoBroker team on 31st Oct, sharing with them my rental agreement and asking for a refund. After three reminders, the team replied on 9th Nov rejecting my refund claim. Reason stated was built up area mentioned in my advt. on Nobroker was 1, 000 Sq.ft. and that in the rental agreement was 850 Sq.ft. I have tried to explain them for last 11 days that built up areas mentioned either in advt. or rental agreement are all approximate areas and that my apartment’s purchase agreement mentions only carpet area that is 57.54 http://Sq.mtr. In any case an 850 area should have got lower rental, but I still got the tenant at more than minimum commitment to NoBroker
