LIC home finance
Can i increase my EMI

I have taken home loan from LICHF, pune] two years back. Based on my salary my EMI was and now also its 19, 580

Now I have enough salary that I can pay EMI of 25 or 30k, on front page .]. I visited LIC office and asked so they told me that we can increase your EMI max by 2000 rs .. we can’t do anything as system [I think their software gives result based on my salary inputted to it two years back ] says like that, I told them that my salary is revised now and I can pay more EMI ..

are they correct?

Thanks
