Hi there, I truly apologize for the inconvenience and frustration this caused. I completely understand how disappointing that must have been, especially after a long day at work and looking forward to your order. Unfortunately, when it comes to card acceptance, we’re at the mercy of our card service providers. While Discover is a debit card, some processors don’t support it consistently, and even with backups in place, there are times when issues occur that are unfortunately out of our control. That said, we genuinely value your support and don’t want this experience to be the reason you don’t order from us again. If you’re willing to reach out to me directly, I’d be more than happy to hook you up with some free products to make up for the trouble. Thank you for your honesty and for giving us the opportunity to make this right. We hope to earn your business again.
