[Resolved]  Bajaj Auto Finance Ltd — cheating by bajaj auto finance

I took a loan for buying a laptop for Rs.33000 from Bajaj Auto Fin, Kottayam.
They agreed to provide a loan for 3300 t0 with 8% interest for 24 months.Accordingily they collected 24 EMI chqs for 1595 each.
After collecting the chqs, they sanctioned a loan for 32440 with 9% interest, Emi for which also comes to same 1595. This they have done without my permission and without my knowledge.
On enquiry they quote different reasons and mis behaving over telephone.
Now I had to shell out Rs.540 extra to the vendor of Laptop plus I have to pay another Rs.540 extra by way of 1% extra interest.
They have not yet issued statement of loan and statement of chqs received with them.
