Pathetic service with ZERO Transparency with how you do business VODACOM

Vodacom staff registers you for contracts then when you call in to find out what was going on and for a manager to call you back as the staff do as they please you get Zero FEEDBACK, Then to top it of you agree to the contract pay for it for over 3 month then VODACOM decides that there staff was in the wrong and cancels the contract. Where did you receive any confirmation from me to cancel this.
