Los of airtime instead of data

<p>Samsung j5 air time is being deleted when my wife goes into whats app or facebook instead of the data. She has been given all sorts of excuses by the care line operator. She has had this phone foe about 2 years</p> <p>and regularly checks her airtime and data especially when making calls or goes into one or another app.</p> <p>Can vodacom give me some sort of explanation because as pensioners we can ill afford this loss of airtime </p>
