Bad customer service for network coverage

I will leave a negative review again because it's been almost a month and my problem still persists. The signal enhancerband router at my house was not installed correctly. I have NO, whatsoever network at my house. Vodacom call me once a week to inform me they are looking at the problem but they never did. I did inform them that the general network in the area is not the problem, but at my house where they installed the devices. But they do not make any attempt to investigate the problem I have explained to them. They did send a technician a year ago Nd they did identify the problem. But since that assessment a year ago no progress. Why am I paying for network services I cannot use at all? Living in a farm, when I have an emergency there is no way I can even contact someone because of my unreliable Vodacom service. And believe me, I will complain every single day until the problem is fixed. And by the way, Vodacom keeps closing my tickets even through the problem has not been addressed aswell.
