TVS Finance — regarding my loan amount

I had huge respect for tvs finance but its gradually decreases. You know i have purchased tvs sport through tvs finance and the total cost of the bike was 65, 600. I had paid 16, 000 as downpayment. So according to me the loan payment will be merely 51, 000 (Processing fees 550) but i saw that my loan amount is 59, 879 which is totally wrong.
I contacted tvs care and they asked me to send the invoice. I said them ok i'll ask to showroom. But later when i contacted showroom, they told that they can't give invoice as they have given to loan company person. They again said it's not their rule to give us invoice if we purchase through finance. However i was disappointed and contacted tvs care again but they said they can't do anything without invoice.
Rabi who was my agent and financed my bike said, the loan amount was mistakenly printed and he has sent an email to ho regarding this matter and said me to wait for few days. Few days later when i again contacted tvs care, they still asked me to produce the invoice. I also asked the same thing - on which basis you have decided my loan amount. So definitely you have decided the loan amount on the basis of invoice but care said the loan amount was decided on the basis of agent's mouth word.
So my question to tvs finance:
1) how will you decide the loan amount on the basis of agent's mouth word?
2) why you couldn't ask for the invoice while you were deciding the loan amount?
3) why you are making people suffer?
4) you should have common sense that tvs sport price can't be rs. 74, 000.
5) why you can't able to give loan account details before collecting my emi.
6) i was shocked to see you had taken my 2nd emi but couldn't provide any paper or email regarding my loan account details along with emi, interest rate.
So our honorable department (Indian judiciary system), please enquire them otherwise it will lead to huge destruction. These kinds of loan companies will make people die.
