Kun Hyundai — Fraudulent activity in utilization of my loan emi cheque

Address:

500008

This is leela Manohar Gokavarapu, i had purchased an Hyundai - Grand i10 - Sportz - Star dust Color (T/R - TS09AATR 5124) from Hyundai Show Room - Krishna Plaza, Khairatabad, Hyderabad, Telangana 500008, for this i got loan from SBI Car Loans of Rs.5lac with the EMI date on 15th of Every Month.
in this regard they insisted that i have to submit Blank Cheques as per their Norms to deliver the vehicle on 5th Jan'16 . Hence i submitted the same to Mr. Ramana & Mr. Rajesh - Loan Processing team, to debit monthly EMIs from my Account ( Bank Of India ). As per the Loan documents received by Hyundai they supposed to debit the EMI on 15th of Feb'16, but with out my knowledge they deposited the cheque on 12th Feb'16 which causes additional Cheque bounce charges and my Loan History was spoiled due to this. when i ask them to give clarification on this they stated that " do what ever you want, we didn't bother about the complaints and we know what we have to do".
hence kindly help me on which they ruined my Bank / Loan Profile and guide me further about the remaining EMI process.
