Vodacom is useless!

I logged a ***** case and it was closed as a sales dispute. I am now getting calls from Vodacom to demand their money for the ***** contract. I have called customer care and I have called Vodacom legal and no one can help me. This is the absolute worse company to do business with and they make ***** so easy and people are getting away with it while the innocent have to deal with the consequences. Do not engage in contracts with Vodacom
