VODACOM - USELESS as USUAL

ONCE AGAIN, VODACOM DON'T FAIL TO NOT do their jobs properly. Cancelled contract for data end Nov and still been charged. So I must wait for someone to answer my call to then be told oh, sorry!! then I receive an email to say that this will now be a 'pay as you go' NO NO!!!!! Then try and phone again and can't get through to right department, tells you to dial different numbers but NOT the departments I want. Plus on origianl call get passed from pillar to post SOOOOOOO over this!!!
