No internet

I called in more than 3 times yesterday, and sent messages on social media and my network keeps going down. Supersonic says that my router is showing red light and down cause on their side it shows that I moved router to a different location, which is not true. I have never moved this router to a different location. I spoke to 3 agents, who would switched on the network on their side, my internet would work for an hour, then it goes down again. I work from home, and now I could be in trouble at work. Supersonic could you please fix this Issue, my email is *** and passport number: CN058864 tel: ***. My address is 75 kasselsvlei road Bellville, cape town. Please call me.
