Highly disappointed

I have been on the unlimited data LTE package for over 2.5 years. Received a call last Tuesday confirming from *** that I may continue for another 2 years on this plan. Also confirmed the debi order as per messages received. Only to find out earlier today that I have no data as my data has all been depleted for the day data. I am confused as I did not revert back to any old packages and was assured I will be on the same plan as the last 2.5 years and I agreed to the agent on the call as such. Now I sit without any data to watch TV. Telkom can't even retrieve the previous invoices on their side to see what I was actually paying all this time!! Telkom agents whom I spoke with today also cannot tell me who changed my package without informing me properly!
