TELKOM IS *****ING MY DATA!

I obtsain my WiFi via a Top-Up contract with Telkom. Last month I ran out of my usual data and had to Top-Up my WiFi by making a once-off payment. On 1 May 2020 I got credited with my monthly data as I should, however I still have around 50% of the Top-Up I purchased, Now I notice this morning that Telkom is not allowing me to Use up the Top-Up purchased and which expires in two weeks time. Instead it has gone straight into this month's data, which only expires on the 31st of May 2020. So I see myself sitting around the 20th of this month, again with no data, I have to purchase more data, while Telkom is robbing me right now of the data I purchased last month. Stop *****ING! Stop *****ING! Again I say to Telkom, Stop *****ING!
