Telkom network issues

Good day

I have 30GB in total on my pocket router but today I cant log in because it says I used my 30GB. On my telkom app it shows I used 30GB but on the screen itself it shows I used 22.62GB. It is very frustrating that I cant connect to the internet now. I tried purchasing more data then it just give me an error. I tried to speak to one of the agents through the app but I still get the same error. I'm really fed up and would like this issue to be resolved immediately.
