TVS Finance — Recovery agent rash and irrespective nature and talking

I am a finance holedr for a two wheeler in Miryalaguda. I asked the recovery agent to postpone the date to 20th june, he called me on 23rd june regarding finance, i said i am planning to preclose the finance please wait. He started talking without respect, and frkm the biggining of the call the is speaking rash. Due to that as he started absuing even i started. I applied for the memontrium during lockdown that was declined, eeven though i didn't even complained, immediately after lockdown how can somebody pay all the finance, even though i said I'll pre close he is shouting and saying that this is not you own finance in an absurd manner. I don't understand why this bloody agent don't give respect to customers. This happened not only with finance even with service people. I need an answer why my menontrium is declined, previously 2 times i topup my account with the amount for EMI, that was debited on the date and again on next day credited to my account back and check was bounced. If i don't get an answer form the authority I'll go for a legal action on TVS FINANCE and as well on TVS SERVICE.
