DATE & AIRTIME ******

Good day, <br> For the last two weeks whenever i load data or airtime then it disappears under 5 seconds. i have called vodacom and they have merely told me its my settings. I went into the iStore and they said it could be my settings but there is nothing else they pick up, i then changed all settings to the point where i had nothing active. This is ridiculous. I now believe that numbers are being copied and as soon as you load airtime or data it gets swiped from your number. I am very upset about this. i believe this is a vodacom matter. I have called vodacom and asked for *****, or asked if i could log a ********** error on my number, but as you know our customer service, i was not helped efficiently. I have a reference number for my call and they said they would sms me a reference number for my 'ERROR\ but still no sms. i cant stand this
