Dewan Housing Finance Corporation [DHFL] — Dewan Housing Finance Corporation [DHFL] Unethical behaviour, charging of predatory rate of interest

Address:

Hyderabad

I had taken a home loan from DHFL in 2015 for Rs 1655409 for a period of 28 years. My loan code is 00004238 & current interest rate is 16.67% .
DHFL kept increasing the rate of interest and tenure on my loan without consulting me and it is now till shows 28 years duration. After paying EMIs regularly for 6 years, still principal of Rs above 1600000 is outstanding. It is unfathomable that 6 years the duration has expired but the principal has only seen the reduction of less than 50 thousand rupees, which is less than 3 percent. I have contacted DHFL multiple time regarding to reduction of interest rate, but they are dined for the reduction.
