Bad service

I have the worse experience with vodacom from start to finish they **** about the line rental amount they have not contacted me in 3 months and deducted a huge amount from my account with no invoice for the line rental I had been having the run around from getting my box connected and when I try to speak to anyone about the high bill I had no one can help me I want to get out of this sign up with vodacom but no one can help you at all. This is a horrible experience
