CONTINUES PROBLEMS WITH WIFI/FIBRE CONNECTION

I have been on the phone half the day with MWEB, using up my airtime, having to purchase every time I get cut off, and spending 30 minutes on hold before being connected to an agent. Then I still get cut off while talking to an agent. I have been explaining my problem and I am frustrated now. I have endless problems with my Wi-Fi and it keeps loading/buffering and then it takes forever to connect. It does not even allow me to connect from my room which is so close to the rooter. This is most frustrating and I have to pay all that money for something I am not getting the benefit of. If I had to load data, I would have had more satisfaction at this point. How is it possible that NO ONE can phone you back, NO ONE helps you with your inquiry, and NO ONE makes an effort to assist? What should I do now?? I still don't have stable Wi-Fi. this is ridiculous. Can someone PLEASE HELP!
