Life Insurance Corporation of India [LIC] — lic hfl is not reducing the home loan interest rate despite rbi has reduced

Address: Bangalore, Karnataka, 560016

Lic hfl is not reducing home loan interest rate despite rbi has reduced 3 times the base rate, but for my surprise rbi has not hiked interest rate at all and lic hfl already (May be increased one time, but increased 3 folds) increased on my loan. They are offering new loans on lower rate but why for existing customers they are charging high rate even though the loan i took floating interest. I really need home loan rate to be reduced asap and please lic hfl do not cheat customers.
