A Retail Purchase of RMB 10.00 was completed with your BOC Card (-Xxxx) on 21112024, 09:24 at Tenpay Technology Comp. Please contact BOC Credit Card Hotline immediately if you have not authorized it.For info, I tested and linked both my BOC Unionpay Credit Card and Debit Card to WeChat pay, Both are successfully, in WeChat linked Credit Card information, both shows ”Credit Card”. So I guess there in no benefit for using Debit Card in this case, So I dropped the Debit Card.
In China now, Just use wechatpay to test again, working without any problem. So I can pay Card Bill later.
