My DATA KEEPS ON DISAPPEARING

hello Peter <br> sometimes when I purchase data bundles with Vodacom it depreciate<br> soo the last two incidents when it happened I call Vodacom and let them know about it and wanted to know where the problem is.<br> if there is no problem then give me my data back<br> <br> the last time I recharged I bought 250MB AT 21H21<br> and by 21h48 my data was finished<br> <br> I called Vodacom and let the know what happened and they asked me I'd I do updates on my phone I told them yes but only set when WI-FI is connected.<br> and the said it could be my internet ecces and dowloading but the thing I never downloaded anyhting during that time.<br> so the put me thru to supervisors who said will logg a call and get back to me in 24hours.<br> but they haven't gotten back to me and its more than 48hours<br> the disappearing of my data keeps on reoccurring and Vodacom has no explanation to why it is happening.<br>
