Samsung device purchase with extra $600 savings

Last night I tried over and over again to buy Samsung s26 ultra with the $600 savings on top of trade in value. It was a promo that was set to expire yesterday. When I could not get it to work, I tried claimed the members reward promotion which was also a $600 savings on top of trade in value on any plan. I received and email about it and used the link to access it and the website became unresponsive to me. When I would try to access any of the menus it would go to a blank white screen with and error. On 8/24/26 I chatted with an agent to verify if the promos last through the entire day 8/25/26. He said yes it ends at midnight. I was trying to complete the purchase agreement with trade in around 830pm to 1130pm. Then the website suddenly worked again but it was showing new, different device promos. I chatted with an agent and he basically said I am out of luck.
