UNABLE TO GIVE DETAILS ON DATA USAGE

I am really upset with how Telkom is treating their customers, I've had a contract with them for the past 15mnths and now when I'm experiencing funny things. I normally get 500MB a month, today is the 6th of the month I'm out of data already, when I called in to find out how did this happen I am told they are unable to see what I used my data on. and I am adamant that I only access facebook, whastapp, google and biblegateway. sites on my phone, and I have never ran out of data. my colleague is experiencing the same thing with Telkom. I believe they are trying to milk more money since my contract is close to the end of it and I'm not renewing it.<br> I still require detailed usage of the \ 500MB\" I was suppose to get as per the signed agreement.<br> haven't said that I also think that I never even got the 500MB I was to get.<br> <br> someone please explain."
