When The Rescission Notice Is Late

I was reviewing files and I noticed that we have a loan that should have had a Right of Rescission but they never received one. Prior to the three year anniversary of the loan, can the customer send me a Notice of Cancellation and request that all fees and payments paid so far be refunded with the current balance due remaining the same (i. e., $100,000 loan now has a $90,000 balance. They would receive all fees paid at closing and all payments and the loan amount would remain $90,000)?
