Vodacom *****s my money

Vodacom is the worst company in the world. I have to call in every month because the staff are *********** and cannot assist with anything correctly. In August I upgraded 2 of my contracts via the online system. Ever since then my account are in a complete mess and I have been charged incorrectly and I always have to call back for the consultants to sort it out but they just make is worse. It has gotten so bad that I am not longer on the packages that I had initially upgraded to. For this year alone I have been calling Vodacom every month with different issues all the time. It seems that no one know what the hell they are doing. The staff are all completely useless and cannot assist with anything. I am always told to wait 7 - 14 working days and nothing happens, except when my debit order goes off and I am charged incorrectly. Vodacom is debiting me incorrectly and I am out of pocket every single month because Vodacom is a rogue that employs stupid people. Please can someone assist me, after 9 months of this **** with Vodacom, I want nothing to do with them anymore. they cannot resolve simple issues.
