Website:	Amazon.in

Hello i had purchesd a hybrid sim slot adaptor of rs 299 from amazon on 24/05/17 and due to some issue i return it on 04/06/17. The amazon said that they have processed the refund of rs.299on 06/05/2017. The amount should reflect in my account by 13/06/2017. And now today is 14 june 2017 i have not got my refund in my union bank of indaia a/c yet.
They gave me the authorization code (Refund reference number) for the transaction-

Jb maine bank customer care pe phone kya to bolte h "charge dispute jse koi cheej nhi hote or na he hum refund reference no ko track kr sakte h"
