Life Insurance Corporation of India [LIC] — loan related

I had taken a housing loan of 10 lacs from LICHFL in 2009 for a tenure of 10 years on floating rate thinking that the loan will complete just after my retirement and will not be a burden. But to my utter disappointment Lichfl had extended my loan period till2021 on the bogus excuse of hike in interest rate. It is clear from different notifications of Lichfl that the interest rate had never been increased ratherreduced by them on different occasions for the existing as well as for the new customers. Lichfl has cheated an old lady like me. I had sent email complaints to the Reg Manager and Area Manager but no positive response. Don't be fooled by their false reduction of rates because their calculation of interest rates has some inherent flaw which will never be disclosed by them. Lichfl is not straight forward in their dealings. Pl beware as they don't have any concern for an old lady like me.
