Bank Of Baroda — regarding my refund amount

Address: Bilagula branch, Chikkamagaluru, Karnataka, 577132

I have purchased one item from amazon and i have returned it back and requested to refund also, they innitiated on September 30 2019, but i haven't received my cash,

If call to amazon customer care they will ask me contact my bank branch, if i go there they will tell to talk with amazobe only, they already given me the refund reference number also. Nearly 3 times i have been to my branch. Still there is no response from them.
