I sent in a submission to NGC and a few weeks later I got an email that read in part:

This email is to inform you that there are one or more coins on the NGC submission listed above that have been recommended for NCS conservation by NGC's graders.

Please review the attachment for detailed information on the coins that have been recommended for conservation. If grades are not provided, conservation is required for the coin(s) to be encapsulated, otherwise the coin(s) will be returned raw (not encapsulated) and grading fees will still apply.

I responded with the email telling them to go ahead with the conservation and charge my card on file. I just got the coin back. They graded it as UNC Details - Cleaned I just got off the phone with them, it was not a mistake and they are not willing to refund me for the conservation fee. I am really pissed off about this and canceled my membership. I am relatively new to all this, am I out of line here? Does this kind of shenanigans happen often and is accepted by the community?
