breach of contract

<p>im very unhapphy with the service i receive from vodacom that is why i did not renew my other contract. my data bundles of 1 gig have been cancelled. when i phoned upgrades they said the promotion was for 1 year. the lady who did the upgrade for me said it is valid for the period of my contract which is 2 years. please go over the call when i made the contract upgrade and what was promised to me.</p>
