Flipkart Internet Private Limited - Order cancelled account blocked which has 600 Rs of gift amount

Order ID OD******************
Placed on **-AUG-****

As the above product was cancelled and i received the mail as
"Hi Sreeram A,

But i just purchased the product for my own purpose. I dont know why they cancelled and said like that.
Problem is I have ***rs Gift card amount in my account but now my account has blocked unable to login.
As i order was rs ***.* used gift card ***rs and Net Banking ***rs.
I contacted the flipkart customer care on **-AUG-****. They said that gift amount also will be credited back to my netbanking account so kindly wait for * working days. Now Problem is i did not even got my ***rs netbanking refund amount. Now i need my Gift card Amount of ***rs but flipkart customer care executive not giving the information about the gift card amount. They just copy pasting the message as
" Hello,

This would also mean that you will no longer be able to login to your Flipkart account.
