Urgent help needed. Visitor visa cancelled 1 month after granted and ban

Hello, I got a UK visa on 21 February 2023, but a
month later I received an email from Home Office
informing me that my visa was canceled, and that
I was prevented from applying for a visa for a
period of ten years.

They said i sent fake bank statements but I sent the real bank statements. What should I do ?

If you can reply to their email, then ask them for for the ‘Document Verification Report’ (DVR).

Else, Complain and ask them for the ‘Document Verification Report’ (DVR).

Else, if it’s difficult to get, then try a SAR.
