State Bank Of India [SBI] — Advance related (vehicle loan ) erroneous charges and interest

Address: 227817

I skipped few installments and when they asked me to clear the dues I deposited the amount and balanced the loan account and increased my EMI also from 8300 to 10000 so that my loan is recovered soon but after passage of Loan Tenure they are still asking for payments and I am not able to identify the exact balance. I want that my account should be properly inspected and all details should be sent to my registered E mail.
