WHAT IS IN THE CONTACT

I have a contract with Vodacom because of issues from Vodacom and myself I have had endless problems. Today my phone has been suspended because the account is in arrears because of 2 top up numbers that expired in July 2014 and Sept 2014 and have never worked since. Up until February 2015 I paid for these 2 top ups (not being able to use them) and request why should I carry on paying for them if they are non usable.<br> <br> Today I get toId I have to cancel them with Voda but they have already suspended them on expiry?????? or carry on paying for something that VODACOM HAS ALREADY SUSPENDED???
