Onstar can't find my VIN in their system. Brand new vehicle

I've had this new 2024 Colorado for almost a year. Since "new" onstar has not been able to activate my remote services. Just got it back from dealer again and they assured me all is well with the onstar module. Tried activating yet again and still have same issue. Onstar gets error message while searching for my VIN. I've verified the vin 3 ways...tag on windshield, tag on door jamb, and window sticker. All match. Not sure how GM can't find their own vehicle in the computer. Onstar will yet again elevate this problem....I just want the services promised on my window sticker "3 year remote services included" 

Any ideas?
