Breach of contract over charging

<p>So i signed up a "U Choose smart S" contract because i bought a phone cash and thought this contract is ideal and i would probably let it run for as long as i can.... most likly more than the 2 year.... andyways 24 months later Vodacom decides to cancel my contract without my consent and load me on a new one, one which cost more and gives far less... so initially i recieved 1gig data, 70min talk time and 200 sms.... now i get 300meg data, 75min and no sms... and im paying more for this ****. so Vodacom has signed me up *******ly for all i care, all i want is to be back on my LEGALLY SIGNED contract... the call center says i have to go to a store, cancel it and sign a new contract.... BS Vodacom must resolve this!!!!!!!!!!</p>
