Telkom allocating incorrect data purposefully

I took the 120G Wi-fi package with Telkom where you get 60G anytime data and 60G night surfer data. My data kept on depleting after every 2 weeks and even though no one was home during the day. I logged a call with their call centre to say that something was wrong with my data and that there was no way it could be depleted in just 2 weeks especially when no one is at home during the day. I was told all sorts of stories and I still was adamant something was wrong. I then decided to do my own investigation and to my surprise, today the 1st of April, I decided to insert the sim card in my phone to view exactly how much data was allocated to me and to my surprise, I was allocated 10G anytime data and 61G not 60G but 61G data which was INCLUSIVE of night surfer data. Meaning all along Telkom has been robbing me of my 50G anytime data and thought they would get aware with it. Where can one lay a formal claim like your Ombudsman when in comes to data? To everyone out there, please watch out and don't be fooled like I was.
