Telkom night surfer is a *******- Call center agents bad attitude

I bought 2GB which comes with free night surfer data in December 2017. I only noticed that my anytime data was being consumed instead of night surfer data even though I was surfing between 12-7 am. On the 24/01/2018 i called customer service and i was told that I should've refreshed my phone to interchange from anytime data mode to night surfer. I just let it go thinking it was my fault. On the 26/01/2018 i did all that i was told in order to use night surfer and still my anytime data was consumed. I later reported the matterto customer care line and was told yet another story that i should not be on data roaming to access night surfer. Looking back I recall having problems using limited time night surfer data on two occasions and I wasn't on data roaming in those occasion. Information is not clearly stated when we buy data and it is frustrating and dissapointing that a reputable institution as telkom is not transparent on its terms of service. It is also disappointing that after receiving such bad service when i sought for a way to resolve the matter the call centre agent potrait bad attitude. When i tried to report the issue of the agents attitude it turns out that the agents are protecting each other and I never got transferred to talk to the supervisor in charge. I was only told they'll listen to the phone call and come back to me which never happened.
