No feedback after 72 hours turnaround

So I phoned your call centre on 06 Jul 2015, to enquire about why my 1 gig data bundle get depleted within a week after my monthly data loading. Initially when I entered into this contract my data bundle used to last for the entire month, without even having to disable my mobile data on my phone. Recently a week is too long for 1 gig to last, even though I disable my mobile data during the day as I connect through WI_FI instead. Your call centre agent kept on telling me to disable my mobile data, which is what I kept on emphasising to her that I currently do so to save my data bundle which doesn't seem to work at all. I then asked if I can speak to someone who will understand my query and provide me with a better solution, she reluctantly opened a case Number ***0 for me and promise that I will be contacted within 72 hours. Today is the 24 July 2015 and still waiting for someone to contact.<br> <br> I wonder if the case was indeed opened as the agent didn't even sound enthusiastic on the phone. I just wish Telkom should invest more on your call centre agents so that they can professionally and competently deal with customer queries effectively.
