My Pizza Hut Order Seen Delivered While It Wasn't. I Paid It Online

I placed an order for pizza through Pizza Hut's website. About 20-25 minutes later, I checked the order status and saw it had been marked as delivered. Confused, I immediately called their customer service to clarify. I explained that while my order showed as delivered, I hadn't received anything. They assured me it was a mistake and that my order was still with the courier and would arrive soon. Another 25 minutes passed, and I called customer service again, this time to inquire about my order status. Once again, I was told it had been delivered. When I insisted it hadn't, they contacted the restaurant and informed me that my order was indeed with the courier. Frustration growing, I sensed something was seriously amiss and asked for a refund. They told me that if I refused the order upon delivery, it would be automatically canceled, and I'd be refunded within 14 days. Losing trust in their promises, I warned them that I would involve the authorities if their courier arrived at my doorstep. It's safe to say this experience left a bitter taste in my mouth.
