E26 Smart WiFi Bulb 10W A19

Took over 2 weeks for delivery. Finally received the package, had to pay duty before receiving. Tried setting it up and although lamp was switched on, the bulb did not light up. It was able to be found by the app, so the bulb was getting power, but the LEDs are faulty. I emailed the company twice to arrange replacement or refund but have had no response.
