Can't use our cellphone we are home.

I have been using Vodacom network for more than 15yrs and as they improve the network service we turn to suffer even more. I stay in Soweto, Emdeni Ext and we have 2 network earials which are not helping us and we just can't use Vodacom network at all when we are home, the network is so weak that I even ported 1 Vodacom number to MTN and my main number still suffers. I had logged a complain and they technical staff checked and told me that. They can't help us, we will only be able to get help after July(financial year end for Vodacon). So now since this is not helping me or our area, I want Vodacom to cancel all my contracts at no cost because its not my fault that I am not getting any network, the company has failed us and I know if I was in a White dominated or rich surburb this would have been fixed a long time ago but because I'm in a. Very poor classified area nothing is going to happen. I need to get a good service and a stronger network signal like a Vodacom customer not as per area I'm at. I am very frustrated to think I must stand outside the house just to be able to access the weak network. Honestly what's the point of having airtime, data that we can't use. Please help.
