Toospoiled: since you're C & A Members, go to RCI"s website C&A Member Forum. From there, login (you may need to create one) and check your Cruise History. From there, you'll find a link to: "Missing Cruise Credits".
If you have completed a valid cruise but do not see it or your Cruise Credits listed, just click on the "missing Cruise Credits" link and fill out the form. A Crown & Anchor Representative will contact you.
Is it possible you completed any of the cruises you mentioned under a slightly different name? If you registered using a variation of your name, it may show up differently. Hopefully this will help you resolve this.
Take care, Steve
