Unable to Complete Purchase on Clinique Website – No Help from Customer Support

I have been trying to make a purchase on the Clinique website, but no matter what I do, the order won’t go through. I’ve tried various products in different combinations, using Safari, Google, Yandex, on both my phone and tablet, even my computer. Despite all these attempts, the checkout process keeps failing, and I’m unable to buy the products I want. I contacted customer support, hoping for a solution, but they were of no help whatsoever. It’s incredibly frustrating, especially from a brand I’ve trusted. If this continues, I’ll have no choice but to turn to other brands. Please resolve this issue urgently so I can complete my order.
