Unfortunate returns outcome :(

I returned 3 Meross Smart Wi-Fi 1 Way light switches after discovering that the items are rated for 110 - 120V and not South Africa’s 220 - 240V as advertised on the product information on their site. Despite this I was charged a 15% restocking fee on the one I had opened while discovering this. I would have been happy to accept this if it wasn’t very clear false advertising and I seemed to have been unable to communicate the *******ity to their customer support and returns department.

Over and above this they continue to claim that it will work at 220 - 240V which may be true but an insurance company could easily see this and reject any claims related to an electrical fire.
