Punjab National Bank Housing Finance [Pnbhfl] — very highhome loan roi

I am a loan holder from the aforesaid company since 2017. I have been constantly pursuing them for reduction of interest rate since the last one year through calls but they have not done anything in this regards. There is an employee santosh gupta from client retention team whose conduct is highly undesirable & not fit for this role. They are currently charging me 9.35% against sbi which is 6.95.-7.25%. They do not have any satisfactory answer when this point is raised with them. There can be a minor difference in the rates for an hdfc but it cannot be so exorbitant and arbitrary. They have increase my rate of interest arbitrarily & refusing to roll back & give me a good deal. I recommend strong action against the company for charging me such a high rate & improper behaviour of their employee santosh gupta. They have not shown any interest in listening to my grievances & resolving the same hence they should be taken to task immediately. My loan account no is hou/lud/0817/417608
When i had taken this loan pnb housing finance roi is cheaper then rest all banks then how they can cheat me like this its really bad these type of influence makes defaulters towards bank
An early respose will be highly appreciable..
