Swiggy - Refund for unsuccessful order

I had placed order (***********) on ** June ****, which was unsuccessful, but the amount Rs *** debit from my account. I called swiggy customer support and he said if amount deducted, will auto credit with *to * days. After discussion, I received msg from swiggy;
Your payment for order #*********** was not completed. Any amount if debited from Cards will get refunded within *-* day.
After a week I mail n they are asking to share my bank statement, when I shared. They told me dat ur statement is wrong.. How can they say like this.

It's pathetic, u can talk to customer support only if u have active other, there is no contact number to contact customer care, only chat option available. This is totally harassment. It's like annoying to ur regular customers.
please find enclosed screenshot of msgs received from swiggy and transaction details.
