Canara Bank — women's rayon printed jacket kurta with palazzo pant set

I have purchased one kurti from amazon on 11 may amounting rs. 1399 paid by my rupay card ending with 5884 and the same has been cancelled on 14th may 2019 but the refund has not yet been credited to my account since then. This is my 4th complaint regarding this issue and till yet no action has been taken till now and i m really fed of this kind of issue that i m facing for no reason. I want you to take some action in this regard and plz credit my amount of refund to my bank account ending 5378 as soon as possible as i m really pissed off and i dont want this to happen again.
