Data maxed without usage

I bought 2gb data and as usual I was given 2gb for free around 11am on the 03/03/16.I left my phone on my desk to attend a meeting that took about 3 hours,when I tried to use my phone for my social networks,all my data was maxed to 64mb.<br> I called in immediately around 13:50 to complain on the Same day ,I was given ref no:***, same ref was Sms to me and I was informed to wait 5 working days.<br> I called back after 5 working days only to be told by anele rudely that the case no doesn't exist, he placed me on hold while waiting to speak to a manager for about an hour and then he dropped the line .<br> I called back and spoke to Mpho who confirmed that the case exists but hasn't been attended and she said they still busy with the case.<br> <br> I find this whole pillar to post and different info from same company agents so unprofessional. No one has came back to me regarding my data .i am using an apple phone,once not used on any social networks it doesn't consume any data so I need this sorted out before I decide to leave MTN for good .<br> <br> Someone must take responsibility and resolve this.<br>
