Shocking service on a return of a product

Shocking service received on return of a HD outdoor security IP camera bought from Takealot. Camera was bought in November 2023. I also bought a Gizzu Mini Dual DC UPS 4 days after I placed the order for the camera. I tried to connect the UPS to the camera but the power outlet had no USB port and I decided to return the camera. My return was denied for the following reasons: The camera was dirty and used. I hardly handled the camera and there is no way that the camera was dirty. The camera was packaged in a box, it had no seals or stickers that I could remove and I placed the camera back exactly the same way I received it. I asked the agent to please elaborate on the fact that it was used because it wasn't and I get the same message - my query will be escalated. This has been going on for weeks and almost 3 months later they have not returned the camera.
