Black Friday False Advertising

I purchased 2 bicycles online on black Friday for my kids, before purchasing i did go into the Gateway store on Thursday evening to view colors and verify sizes. My baby girl wanted a pink bike like all little girls do and my son wanted a blue bike. The sales agent said we could purchase online or instore at midnight and colors are available online. So, we left the store as it was 8pm and decided to buy online, but when ordering there was no option to select a color nevertheless, I purchased online afraid that stock would run out. I did reach out to customer care the next day regarding the issue with the colors and they assured me that they notified the store in question (Gateway GAME). Friday 2nd December 2022, I go to collect the bikes instore and was given 2 green bicycles and was told that's the color I ordered and there's nothing they can do to help me besides give me a credit and that I must repurchase the color I require at full price. My issue here is that I reached out to customer care first before going instore to avoid this, and the color that I bought online was blue so who is in the wrong. This is false advertising and poor customer service altogether. My kids where very disappointed and so am I. I have a screenshot with the conversation with customer service agent & screenshots of the online purchase.
