You should be able to tie out the bank's records to yours and vise versa. Pretty simple, really. I just use a red pen, as it stands out, and put a small dot besides the corresponding amounts on each record, their's and yours, and the discrepancy usually falls out by having no match. It's best to start at a point when the reconciliation was already tied out.
We've done that. Twice. Each of us -- the "personal banker" and me. Everything matches. We started at last April, and went through three places since then where it balanced. But thanks.
Steve.
