Loan Mod approved and accepted then mortgage sold to another lender

I didn't accept first loan mod because they were taking me back to orig loan amount without applying payments. After much discussion they reworked the loan mod and we accepted it. However, after everything was signed and sealed, they sold loan to another lender 8/2021 however they have not sent the full records to new lender. We are making payments that are being applied to a suspense account (over a yr now) and they are waiting for the original doc from old lender. I've sent a copy of the recorded loan mod but they say they need the orig. In the mean time, there has been no correction on my loan amount, rate or monthly payment. Its like my file has gone to the black hole of no one knows what to do. How can I speed this process a long? By the way this is a VA loan.
