Vodacom system change Costs the Customer

Please get ERNEST MANYENYE or Nompumelelo Mchunu to call me back as he promised more than 48hours ago. I have logged numerous complaints with Vodacom on the same issue to date and not one call back. I have left my contact details again today with Xoliswa Posile. I am one of the UNLUCKY customers Vodacom moved to there new Siebel system. I have no access to my account information as they have system issues, the system was not ready to go live. I cannot even check a balance on *111# nor the Vodacom app nor the website. Yet I am being charged over R1200 for out of bundle rates. I also requested this contract to be cancelled and they say this new system cannot do this, I am outside of the 24 month contract period. VODACOM Please respond!!!
