Airtime disappears

<p> </p> <p>On the 11th of July 2016, I had R13 airtime and 40mb data at 19h40, I then recharged with R30 airtime at 20h33, but at 20h35 all the airtime was gone.<br />I called customer care, they say they cannot see what took the airtime, it only shows internet, which I was not using, they put me through to different agents but no one assisted.<br />I then switched off my data and recharge my airtime with R30, the purchase 100mb with R15 at around 22h05, at 22h15 all the data and airtime was gone, the only application which was open on my phone was Whatsapp. As I was advised by the technical stuff from MTN to switch off all the App’s and leave the only app am using.<br />I then switched off my data and recharge with R30 airtime at 23h13, then purchase 100mb data worth R15. I never switched on back my data but at 23h16 all data and airtime gone. Called customer care, put between agents all saying the same story that it shows that the airtime and data went to internet which was not even opened on my phone.<br />On the 12th of July 2016 at 09h00 I went to MTN store to enquire, they told me they cannot see anything I should call the customer care.<br />Then at around 09h50, I recharged with R10 airtime and purchase 50mb of data, at 10h10 all that was gone, I then recharged with R30, purchase 100mb with R15, at 10h30, all was gone.<br />Now am even afraid to recharge because I do not know where the airtime will go and no one will have answers to where it went.</p>
