VODACOM THE WORST NETWORK EVER

Its been two weeks now trying to make calls and receive calls on my phone and cant hear the people I am trying to call or who have called but they can hear me when I speak. I first thought it was my phone that had a problem only to find out that several people from where I stay are also having the very same problem with the Vodacom network. I called the Vodacom costumer care centre for assistance they told me to get three neighbours who are going through the same problem, I did as they asked then they changed they story and now said I should get Five people. My neighbour called the customer care and they said to her they will call her at 7PM two days back even now she is waiting for the call from the lady who assisted her. They then said we must be in the area that is having the problem but how could we have called if we cant take out calls or receive calls from that very area. I have lost many clients because of this problem, the Vodacom number is the one I use for business.We are planning to change our network and advice those using Vodacom to do the same because of the bad service we received from them. what is the use of having a phone you cant take out or receive calls from
