Rto Wadala Mumbai — License not received

Address:

Mumbai City, Maharashtra

I have given my Driving test for Four Wheeler at Wadala RTO on 2nd January 2015 & passed the test. And it was informed by Noble Motor Trainig School that License will come directly through postal service within 45 days. It has been 6 months now but I am not able to track my License, even the agent is refusing to answer since there is no tracking system for license. I visited 2 times RTO Wadala office but they are also unable answer. I do not know what to do. There is no toll free complaint number nor any rto's email id where i can share my problem. Request your help. Attached my registration challan.
