Vodacom Fibre installation is a Nightmare

Vodacom fibre with openserve is the worst i have recieved my vodacom router 2 weeks ago i have been waiting for the openserve technician to come for fibre installation i called vodacom customer care for assists and they said a technician will come within 72 hours , i then called again after a week i was told that the matter has to escalated to management the matter will be resolved within 72 hours, Yesterday i called again for a follow up the agent to me to me to avoid calling customer service as it delays the progress , this has been an inconvenience because i work from home i cancelled my subscription with rain 5g , thinking i would recieve a better service with vodacom but instead i have to buy data bundles every single day for me to be able to work, yet i see Openserve vehicles around my area every single day i went to one of the technician to ask why haven't they come and install my fibre and i was told that because i made my fibre with vodacom they can't help me unless i cancelled my subscription with vodacom, and start a new application with them then they'll help me this is totally unacceptable because im stuck with a router that doesn't work yet the money is still going to be debited from my account month end
