My hdfc bank loan-two wheeler loan[protected]. I already submitted the loan emi rs. 2765 every month but extra money is also deducted 3 times. I need the clarification why this amount is deducted when i timely give the loan emi's. I many time call your customer care but they don't resolve my problem.in my account sufficient amount of money is available all time for loan emi's then why you deduct extra money.
