Well, here's a new e-mail response from Frecuenta. I received my card in the mail, then requested my PIN by e-mail. They sent my PIN number two days later. I then e-mailed a second time requesting the transfer and this is the response I got.

"Thank you for your e-mail. The request to transfer 5,000 kilometers from
each Frecuenta account to 10,000 Hilton Honors points (each account) has
been requested. Due to the heavy call volume that Hilton is receiving, we
have been advised that transfers are taking up to 4 weeks.

Your patience is appreciated.

Thank you,

Mexicana Airlines
