DIsaster Cell-C Fibre Network Continues, with half done job

Cell C is a disaster, I don't know how many times I have talked to their technicians who promised to fix my connection problem and it seem to be getting worse. I had thought this time around the connection has improved since they changed the Router but i seems now its getting worse, only a TV has a connection my laptop is restricted somehow only them know what they did. I have suffered with very bad internet disconnection every 5 to 10 minutes for two weeks and no one has tried to fix it. I complained to a lady named Charlotte who promised to forward the issue and I haven't received any assistance. The only thing I received are invoices for me to pay when I have experienced a disaster service the whole month. I contest paying for this very poor service this month, you know very well it was a disaster and I had worst service which is legally not worth charging me over. I was promised to receive technicians to come check but I am still waiting. I am tired of this nonsense, Xycel Router, Technicolor for some reason never gave me two much issue for months, whats happening with Cell-C Fibre. Whats so difficult about fixing this network or connection issue to be balanced, it seems someone has limited my laptop connection and transferred it to a TV, cause the TV is OK, but laptop network is a disaster and I need it for work and entertainment and it has slowed my work. I need a refund or not charged this month period until you fix this issue and effective immediately.
