When is Vodacom Fibre going to improve their shocking service?

I had Vodacom fibre installed mid-August, 2018. From the very start I’ve had problems with their service or non-service. A few times when I’ve called, I’ve asked to speak to the manager, who is never available but never returns your call. His name is Jaydee. There is no follow up to complaints or no reference numbers given. I complained on the 9th October, 2018 that the installation was still not complete. Nobody has come to fix it. My main problem is that internet is going off at least 15 times a day. You are busy downloading something important, when the internet goes off and you have to start all over again. I app**** to have my landline ported to my fibre line but I’ve received nothing from Vodacom. I thought Telkom was bad with their ADSL, Vodacom fibre is far worse. The signal is not stable. When you have to call Vodacom fibre call centre you have to call a cell number. If you are not a Vodacom subscriber you have to pay cell phone rates for the call which usually last about 20 minutes. This is just not acceptable. What is going to be done about the shocking service from Vodacom?
