Faulty Product, Never used

Description of fault: The device is not connecting on my Wifi Router This is the only reason for purchasing this device but we cannot get both the ONT and Wifi router working on this device When both are plugged in on a 2/ 3pin plug onto the device, the device connects for a second then show "ERR" We did try the phones are working but this device is not required for that purpose as we have battery packs for the phones

I did send a request to Triggercraft and Elecstor but have since still not received a response I wasted R1800 By the way all good reviews Now I wonder if these were done by employees So disappointed with service If it was just the product and they rectified the issue I would not be writing this BAD Review After Sales Service id everything
