There is no Concept of Unofficial Cibil Report
They are bluffing
This is my Cibil report extract downloaded from SBIHomeloans(not active now)
As you can see the left Header is marked X as SBIHomeloans couldn't add their partner Bank symbol
This does not makes the Report more/less authentic, there is a
control Number on right which you can quote.
The partner Banks attach their logo. That's it.
