[Resolved]  Kissht — they stole my money and didn't respond properly

I am paying kissht emi from last one and a half years, i have done most of my payments through upi. This month also in the same way i paid by my own by upi on time to not to get penalized. But even after i made the payment kissht stole money from my bank account. And that payment details was not reflecting in my app. So i contacted them for help, but they made me wait like a dog for my own money.

Luckily i have my bank statements which is saying the money was stolen by the cheating company called kissht. Please help me how to file a proper complaint on them.
