SBI — Charging me over due month on month

Address:

delhi

I have agreed to pay my dues in 12 emi & i am regularly paying as per the agreed terms but still every month SBI is charging me over due amount and my outstanding after paying 9 emi's is equal to what it was before 9 months.

I have paid 80% of my outstanding but still they say your outstanding is 100%

also i have emails then more than 8-9 times and only 2 times in last 8 months I have got revert from them that they will check and do the needful but they are not solving my query.

I have mailed to MD, Nodal officer, customer service head, chairman but no one is bother to revert or solve my query.
