Charging for things without authorisation

Dear Vodacom, I have complained numerous times about a handset fee that you keep charging on my account, I have since upgraded and now you are again charging the handset fee which I DID NOT APPROVE! I am really sick and tired of the lack of service I am receiving from you guys. I have not received statements for the past YEAR!!!(O But no one is getting their statements) If you do not correct both of the things I am complaining about I am hereby officially warning you that I will take this to social media and also NOT PAY MY ACCOUNT FROM THE END OF THIS MONTH!!!!
