Telkom no service for six months

I have had my Telkom internet switched to my new address six months ago, from the moment it was moved I have had very weak and erratic signal , with extreme ping, I have reported this weekly and get told that they'll log it and send a technician, I have not seen a technician for months and, they say it has been fixed but never has been, I have tried their Facebook, and get asked to be patient they'll get someone on the job. Still nothing, I've been told to buy a new router, and that made absolutely no change, I've been told to buy a new phone, same story.The service is non existent and they still have not fixed the problem, I'm expected to pay a packet for lack of service, I have never received such poor quality from any company in my life, and promise after empty promise.I need them to permanently fix their problem, without excuses as they are expecting me to pay for a service when I am not getting one worth R50 let alone close to R600
