OP here with a few responses to the previous posts...
The KOA website is not set up to allow you to send the gift certificate to yourself. It asks a for the recipients name, e mail and you get to put a brief message to them.
When I called them back, for the fourth time, yesterday I spoke with the same woman and she knew immediately who I was and the problem I was having. She then issued the certificate sending it directly to me and lo and behold it is dated December 30th confirming that they had never sent it in the first place. If one had been previously sent they would have resent it so as to not have two separate certificates floating around out in cyberspace.
I posted this experience to share with others and as a warning as to what you can expect if you try and deal with the KOA website. The pros and cons of staying in most KOA's has been beat to death on this Forum {and others}, and I feel no need to go there.
The Moss Landing KOA {located between Santa Cruz and Monterey}, was very nice, great location and consequently very busy allegedly year round so reservations are a must.
