TERRIBLE TERRIBLE NETWORK

I have complained to Vodacom 3 times via Facebook and once via Hellopeter and my issue is still not resolved. After my complaint on Hellopeter and a few calls later I was sent an SMS to say the radio planning team would be in contact. That was sent 04/02 and I have since not heard back from anyone. I am paying for data that I cannot use. You will notice that very little was used in Feb. As advised previously if this issue cannot be resolved then I need to be allowed to exit my contract without penalty. I am not prepared to pay for something that does not work! Please contact me urgently as to the process to cancel. Others in the estate that I live at have communicated with Vodacom. Techs have come out and confirmed that the problem cannot be resolved. I need to cancel and move to a network that actually works. Please contact me URGENTLY in this regard.
