Fullerton India — NOC not received since 3 months

Hi Team, This is regarding a request I have placed for a NOC, which has not been received since 3 months and have been put through the worst experience, the courier containing the NOC has been returned stating "ADDRESS IS INCOMPLETE", wherein I receive other couriers fine. When asked for a scan copy of NOC the Customer Care has advised me to scan the RC book and send it, why am I being asked for the same information over and over again, this is the worst service I have faced. I would never advise anybody to be go for fullerton loans with the experience I have received. Why is it so difficult to send me a email copy of my NOC.
