Magma Hdi — refuse to update pan/ sanction car loan without pan

My name is pradeep kumar rana & my pan no is aihpr5406q. I have no any loan with magma finance, but a loan no. (Pg169c1400071) is showing in my pan (Cibil).
When i searched with my side, i found that this loan belongs to eahps7102c & his name is pradeep kumar sharma, but by chance we both person are belong to same state, same district, same po, same ps, only our village are diffrent. When he buy car through magma finanace has not sumitted his pan copy.
Now when we both visit magma branch at jmt (Jhumri telaiya, jharkhand) has refuse to update pan & say to me why i update... Ur problem is in your cibil... Go & solve it personly.
I am living in faridabad (Haryana) from last ten year on rent, now when i apply for home loan this mistake has block my all option.
Without updating actual pan of concern person. My cibil is badly effected. No one bank agree to give me loan.
This a big fault of (Magma finanace) pls help me & pls take action against branch incharge at jhumriteliaya (Jharkhand), how he sanction a car loan without sumitting pan or any other documents.
The car no is jh12f8952 (Maruti alto 800)
