Am I SOL? Expired Citi Costco cash rewards.

I’d like to start off by saying I know how dumb of a move this was on my part. Although there was plenty of heads up, I was unaware that the Costco cash rewards had an expiration… I had several hundred $ in points from 2023 that I was hoping to stack on top of what I accrued in 2024. Well now I have learned that they have expired. Costco is happy to give me a shop card in replacement but they need a barcode to scan to do so. I’m assuming this is because they need to confirm I have indeed not redeemed it yet. Problem is I am not enrolled in Estatements so I am told by Citi bank that the barcode was sent in my February and/or march statement. Well I cannot locate those. So am I SOL? Has anyone done something so idiotic is as me and have any experience with this situation? Citi says they have no way of replicating the barcode now that it’s expired, but can’t they look into my statements and see I haven’t redeemed it? Any advice is appreciated thanks guys
