Bad Service from Supersonic

I am 2.5 months with supersonic and my internet connection was cut on 27/08/2020. I am having a nightmare trying to be reconnected. Everyone i talk to start me from scratch and another one by the name of Chris called me and asked me to be in front of the router at 4pm yesterday and that he will call at that time. i left my job to wait for him he never called. Every time i phone i get different answers. Its so frustrating
