Lack of assistance - Data issues

I have a serious issue with the my data being depleted at a rapid rate, I have done an escalation and I have been to store and I have called your contact cntre. My data is literally just going down as I watch, the guys at store have checked and they cannot confirm why it is going down because nothing on my phone is on that uses a lot of data. I cannot afford R150 a day on data costs. I am a high end customer yet I am being told this could be 14 days before it is resolved. I cannot wait 14 days for it to be resolved!!!!!! I am cancelling my debit order right now and will be reversing any debit orders that go through because I cannot seem to get assistance. I would rather be on a pay as you go package if this is how you treat your customers who have been with you for ages and who spend good money. Thanks but no thanks
