Incomplete product and very disappointing after-sales service

Ordered a GameSir Nova 2 Lite controller from 4EvaTech and paid on 30 June 2026. I received it around 16/17 July.

When I received it, the box had already been opened and the controller was missing the USB-C cable and 2.4G ****le. The packaging/product also looked different from what I expected from the advertised product. I contacted 4EvaTech on 17 July and immediately provided photos and videos.

I requested a return and refund. Since then, I have repeatedly been told they need to "check with the supplier." I was promised feedback several times, but nothing has been resolved.

As of 20 August, more than a month after reporting the issue, I still have the item and they still have my money. On 19 August I was told the supplier "hasn't been active lately."

I understand they may need to deal with their supplier, but that shouldn't leave the customer waiting indefinitely.

Their own website states that incorrect or defective items can be returned and that they will cover return shipping where the issue is their error.

I simply want to return the item and receive my refund.
