Can the bank increase a mortgage rate after signing a agreed mortgage rate?

I am a 70 years old retired person. Me and my wife have been an investor with HDFC Mutual fund since September 2016 and had high regards for the Fund . I started my investment with HDFC Prudence Fund - Dividend Plan. Until 2018, the fund had been giving me consistent performance . Post SEBI circular dated October 6,2017 on “Categorization and Rationalization of Mutual Fund Schemes”, HDFC Prudence was merged with HDFC Growth Fund to form HDFC Balanced Advantage Fund . We are of the firm opinion and belief that we have been lured in a deceitful manner by the misleading information published in the pamphlet of HDFC Mutual Fund dated 20 June 2018.Thereby , we incurred huge capital losses to the tune of Rs 57 Lakhs (jointly by me and my wife) due to continuous non performance and misfit fund,HDFC -BAF wrongly pushed to us by HDFC saying that it retained same attributes and investment philosophy of earlier performing HDFC Prudence Fund. We are seeking justice and guidance on the matter
