5 GIGS depleted in two weeks

I received an sms today from Telkom Mobile stating i have 500mb of data remaining. This is very odd to me as it is not even halfway through the month and there is no way I have gone through 4 and a half gigs of data already. my contracy gives me 5gigs monthly.<br> <br> When I called the call centre the first time around, the call centre agent dropped my call after i had waited for a while. They have my details but did not bother to call back. Rude and unprofessional. I called back the second time around to request that they let me know what sites I am spending this data on and they were unable to assist me with this.<br> <br> I'm extremely annoyed. I spend quite a bit of my hard earned money at Telkom per month and they are unwilling to assist with a simple request. All other networks are able show this information. How else am I to know where and how i am spending my data? I feel cheated.
