Slice Credit Card — Refunded amount

Address:

Bangalore

Hi sir/madam I'm facing an issue with slice..
My repayment is always on 5th of every month so on 15th June I made a purchase on Flipkart of 5000 rupees. Later i cancelled the order and Flipkart refunded the amount to slice so later my bill was on 5th of July. Then I got my money refunded on 4th of July.. but what I was shocked to see was in my repayment they say that I still have to pay the refunded amount including other payments I made... And they just kept on adding interest rates.. I've been called by the company many times to pay... They're threatening me that they'll visit my address... Please help 🙏
