Vodacom again and again

Yet again with vodacom. Last night the money for my contracts was deducted but on my one contract vodacom *****ed up and went and put my one contract over to prepaid without any notice or consent or any means of agreement. Ive spoken to a supervisor this morning who told me I have to wait untill wednesday next week so they can try and put my number back on contract and if they arent able to then the number will stay on prepaid. I mean this is really ****ing me off now. I use my phones for work and can not be without contact on any of my phones as I will loose business. Vodacom needs to resolve this matter right now. How can they **** thing up in a matter of minutes but it takes days, weeks or months for them to set it right. I need it fixed right now Im waiting for them to call me and set it right right now
