Vodacom poor call quality and call drops two days no resolution

Called vodacom yesterday the 25th to complain my line is going silent after 3 to 4 min then dropping calls. The agent tells me to restart my phone. I found it bizzar but I did it. Today it happened the entire day then called the call center now spoken to Nora at 22 20 and while on the phone guess what it does the same thing. I've advised her that the vodacom page on FB is filled with complaints about the exact same issue and someone needs to seriously look into it. She tells me she will send it to back office but provide no ref number. I then asked for one and she says she will call me back. I am a vodacom red plus customer and I'm not chuffed by the service. I cannot bare the fact you claim to be SAs leading mobile provider but offer terrible service and call drops.
