Contour®plus Elite Self Monitoring Blood Glucose Meter Set (with Free Gift) (random Package Delivery)

The delivery service is awful! have not yet received the product (supposed to be arrived two days ago on 3/5/23) until now this moment (5/5/23). Yet, the system now marked delivered. How can I get back my product? No one answers me after two days! Where is my product? This is an expensive item please and I urgently need it!
