contract with MTN

<p>After i had finished my contract for two years with MTN, they called me for another oppotunity for a phone upgrade, i explained to them that i dont need another phone or anything that will bind me for another two years. So they insisted on giving me airtime and sms's, stating that i can cancel this at any given time. one year later i call the service provider to cancel they tell me that i cant do that because i agreed on a two years contract that i didnt even recieve documentation stating those conditions.</p>
