The previous contract was asked to be cancelled and the Smart S new contract said 75 X 2minutes anytime with 200X2 sms's and 200X2 mb data.<br> Now she said that there was never such an offer.<br> Vodacom's Gerald said that there was such a offer.<br> Sandra made excuses and said that she is very busy, after we spoke to her several times and she promised to phone back.<br> She promised Saturday that she will phone us Monday, 9th March.<br> Up to 15:30 no call.<br> We will cancel the contract as it is different that was promised.<br> The contract document does not say anything about what is included and does not even looks like a contract document.
