Cashbus — Regarding refund

I have padi twice repayment by force made by cashbus agents however they r not attending my calls or reply of my mail.
Customer care number is showing wrong on websitlte while in app no provided is not picking up my call.
Where and how to contact them?
If a customer late on due date they are harrasing by every method on every half hour. Violating rules nd guidelines of rbi Google Play Store and nbfc.
