You will have to gather evidence to corroborate that your documents are genuine. You can send supplement documents like pay stubs, IT returns, bank statements reflecting the payments made and the corresponding entries in the bank.
Also, get more documents which reflect the entries, like your credit card statement, payment made by check, and the copies of the check, which should be with the bank.
Also make sure that you send all documents in coloraturas scan.
Get a new statement form the bank, and also send an affidavit that the document is true copy you received from the bank.
