No feedback since 27 Mar 2015

I am extremely frustrated with the service from this company. I logged a query on the 27/03 regarding a billing concerning data usage. To date there has been no feedback.<br> <br> I am due for an upgrade for the last 4 months but will not be considering upgrading.<br> Yet again my bill is not correct. My Aug bill reflects an amount payable of R1680.59 of which R550 is for data usage.<br> I check my bill on a weekly basis. When I checked all was fine and I had unbilled calls of R30. at the en d of the month this moved to R550. How is this possible when I purchased 2 gigs of data and checked my usage all the time to ensure I always had data.<br> <br> I want to know what happen. what was the data used for and I want the bill corrected for both these months.<br> Please treat this as urgent.<br> <br> I want answers before a payment will be made.
