Almost a month waiting Vumatel/Britelink cannot install fiber connection - No way to get a response

The experience , still on going has been frustrating right from contracting . Not knowing the status of contract is placed or not. Vumatel said placed, cell c said not received . 1 week lost. Then installation guys came (they are the only responsive part in Vumatel) connected the cable and modem . followed by splicing guy who again was responsive but could not splice as there was no signal. 2 weeks gone. then i was asked to connect with Linkafrica to install a new line or resolve the issue . And then the installation guys came back again and completed splicing as sent a request for remote configuration. back came the reply that some ONT is not live. then splicing guys came again and have supposedly set it right. Now for last week i am calling Cindy & Sihipwe from Britelink and Robert from Vumatel multiple times a day and several e mail but no response. Neither are the calls answered nor mails rep****. This is the worst customer service culture i have seen all my life. Can anyone help me with how to resolve this?
