Recently my info was jazzed up, two Captain Circle numbers, one with too few cruises and one with way too many (I wish)!
I called and the person that answered took a considerable amount of time with me we agreed on the number and she said she would cancel one record and get it corrected and I'd be set. I was impressed with how helpful she was and very willing to make sure it was correct. One cruise was from 86 and she had that listed.
I would definitely call them and explain the situation.
