Slicepay — Gift card generated without my knowledge

On my slicepay account I saw yesterday that 47000 gift card has been generated which I don't know of. I had applied for slicepay credit card but I had not recieved from approx 8-9 months. Regarding this I used to get call from slicepay. Likewise yesterday also I got a call and after sometimes I saw that flipkart gift card has been generated which I haven't done. I have filed a dispute on slicepay but I haven't got any response from them yet. This is gift card so it can be traced back and get the money back but nothing has happened yet. This is a huge amount for me to repay and nothing has been done to help me. Please look into this matter and help me out as soon as possible.
