Before initiating action, send a request letter under Registered Post Acknowledgement Duet through Post Office (not by courier howsoever big that may be) addressed to the Chairman of the ICICI Bank explaining your reasons for clarification.If you do not receive reply, within reasonable time, you may initiate action duly submitting the related documents like your letter and acknowledgement received from Bank etc. as per the procedure noted in the above FAQs by Reserve Bank of India.  

ICICI is not a small bank in India and is having service back up by most eminent legal experts and the floating rate is not a new concept and time tested over a decade.  All rules and regulations are frame within the frame work of RBI directives and a Bank like ICICI can not go against RBI directives , as they have more exposure in housing loans and even the leader.

If you are not happy with the laid down rules and regulations , opt for changing the loan to some other bank which you wish.
