TELKOM - how can I trust their bandwidth metering?

As my LTE internet provider, TELKOM self-service dashboard reported that I suddenly have many, many times more bandwidth available than I thought I had. Of course, this got me very excited, but upon enquiry using their online chat, I was told that it was due to the mobile application upgrade on their side. BUT - this was using a PC web browser. Apart from the ignorance of the customer service agent that I was chatting to trying to explain this, surely this comes down to mis-adverti*****t or incorrect pricing? The same as one would get when buying something at a retail shop where the shelf price is different from the till price?
