ICICI Bank — Personal loan from icici bank

Address:	531023

Dear sir,
I am bhaskara rao adari have taken loan of Rs.520000/-from icici bank.my loan account number was LPVPM[protected].As per bank employee verbal instructions, I agreed to pay the emi from the month of march at the interest rate of 11.29%.
But the bank employees started calling me several times in february stating that I haven't paid emi that to at the interest rate of 11.69%.
Is it correct way to behave with the customers.bank people have taken all the necessary documents for verification.now they were telling that I was not eligible for that interest rate as my salary was low.
Bank people have talked very nicely until I have taken my loan.but now, nobody bothers my version.they were just asking me to pay the emi which paid on 28 February.

Please help me
Thanking you sir,
Bhaskara rao A
