Reliance Netconnect — Migration of Postpaid connection

Address:

West Bengal

I bought a Reliance Reliance Netconnect postpaid connection bought from Reliance World, Dalhousie,Kolkata, i m not happy with the service of postpaid. so i want to migrate the connection from postpaid to prepaid.
thus i visited the same center for the same but they did not receive my application.
But when i communicated with Reliance Netconnect customer care they told me that application can be given to any reliance world. But the Reliance World,Dalhousie,Kolkata rejected my application.
please hepl me regarding the same. i hope you will give me the best solution and will stop such nonson from company side.
