Amazon India — refund of the cancelled item

Address:

Belgaum, Karnataka

I ordered a charger for rs.604 on 3rd july 2017, a wrong item was delivered on 10 the july hence on 11 the july i returned the order. After which i cancelled my order the same day and i got a message saying refund would be initiated but that never happened! In august i messaged in the customer care column of my account for which a mail was sent regarding call to be received from the amazon... But no such call i ever received... And after almost 3 months.. There has been no refund initiated yet neither have i got a call from customer care... I have all the messages n mailed from amazon for the proof of orders i placed...
