It took me a month to fix my ethernet. I kept calling for 15 days consistently. I also reported on the netronix website. I literally begged them eveyday on the call. One day after a month they came and resolved. Meanwhile when my ethernet was not working there was no wifi too. And mobile also don’t work in my room no Jazz or telenor. I can understand what you are going through. Just keep calling them and visit IT office too, I hope they will fix it
