XXXXXX proporcionará al CLIENTE un folio de cancelación, el cual identificará la solicitud de terminación del presente contrato.

my trying: XXXXX will provide the CUSTOMER a cancelation number, which will identify the termination request of the presente agreement.

Please, I'm opened to suggestions, any help will be appreciated.
Thanks in advance.

Thanks for answering, Alondra. At the end I wrote "cancelation number".
