HDFC Bank — personal loan hidden processing fee and interest rate

Hi my name is dhivya from chennai. I applied for personal loan yesterday after verifying the processing fee as rs.2999 or 2.50% and interest rate as 10.75%.. But after the verification completed i got a message for loan disbursement. When i click on the link and verify the details, they gave processing fee as r.5900 and interest rate as 14.75%. So there are differences between the before and after values. And how can i cancel this loan proposal?
