Fix Claude AI Subscription Payment -- 2

My Claude AI Max plan renewal keeps failing at the payment-processing step whenever I try to pay by credit card. The card is valid and works elsewhere, yet the transaction is instantly declined before checkout finishes, so the subscription never activates... (Budget: ₹800 - ₹15000 INR, Jobs: eCommerce, HTML, Payment Processing, PHP, SaaS, Stripe, Technical Support, Website Design)
