Do you mean to say "my face" or just me generally? It seems to me the latter, in which case I would say: Oh, you missed seeing me today, okay ... it is unfortunate that you didn't get a chance to see me and I honestly wish you had. If you really want to just talk about seeing your face, I guess you would say: Oh, you missed seeing my face, okay ... it's unfortunate that you didn't get a chance to see it and I honestly wish you had seen it. Does that help?
