When a financial institution elects to request that a customer provide written confirmation of the revocation on a recurring ACH item, what information must be presented by the customer in written form? Is it enough to just have a statement that notes the customer contacted the company on a specific date?

A copy of a written revocation is preferable, I think, but a signed statement that he or she contacted the Originator on a specific date and informed the Originator that the earlier authorization is revoked should be sufficient.
