Dmi Finance — false cibil and loan data reported for 1.33 l

Now when i'm checking my cibi report there is a loan of ₹1, 33, 787 is reported as dpd for the last 7-8 months (Cibil report attached). I was running behind them for the last 2-3 months but there is no proper email or response from their end. They have clearly stated that the loan does not belong to me and it was their mistake (Email/chat screenshots attached). When i contacted them 2 months back they were told me that it will be fixed in 30 days but even after 30 days, there are no email or response from them. Then i tried contacting them again and the same story is still going on. This is really important for me to fix my cibil.
