Amazon India — Refund not got since few days

The shoes I ordered has been returned and the money is refunded to my account but I have not received the refund.please check this.
However the delivery man took my jeans also to return but there is no track of jeans and has not been returned as per the site.
My amount is stuck and I am disappointed with your service.
Also, when I tried reaching your customer service I couldn't connect and my account has been temporarily blocked.
Please take it seriously and resolve my issue as soon as possible.
