Bajaj Finance — Other person's loan overdue reflecting in my cibil report

I have availed the cd loans vide nos: 4030cd00070435 & 4120cd1792291 from bajajfin. one loan has been closed and other one is in active & my repayments are on time. but, recently, i came to know from my cibil report that rs. 1166 is showing as overdue amount for the loan ac no : 4120vs[protected]. this loan account number is not related with me. but showing in my cibil report. hence my cibil score got affected. kindly solve the issue immediately.
