Very dissapointed with Telkom Mobile

I have been using Telkom Mobile for the passed 7 years from 2012. I had different Wifi routers and different Telkom contact numbers due my routers being ******. I would buy once off data bundles which gave me extra data for night surfing. At 00:00 When I logged in my data automatically switches to night surfer. Now recently I bought 2gb and surfed the net at midnight. My daily data was finished the following day and thought maybe my son was using my data. I bought 3gb and the same thing happened. On the 16 November Sunday I bought 2gb again then it got finished today the 19th November. I called Telkom to find out what's happening because my once off daily data gets finished. It was confirmed by their agent that my daily once off data is the one being uses at midnight instead of my night surfer, and was told everytime I log in at midnight I must switch off switch on my router then I'll be able to use my night surfer data. I was ****ed of because I never had this issue before. What made it worse is that knew a told I must stay until 00:00 midnight to log in on the internet then call them to see what's happening because they can't trace or see what's happening when it's during the day. I'm really really disappointed when looking at the amount of cash I spend for data. This has never happened before. What worries me is that this is a network that I have reliable to. Actually 3 consultants confirmed that night surfer data wasn't utilised but my daily data is the one being chowed. I stay at night to surf the net with the hope that all is fine only to be told this nonsense that never happened before. I need this to be resolved. I have never been so dissapointed in my life and didn't expect this from a brand that I so highly appreciated. Someone must resove this issue. I can be contacted on *** because my telkom number is always on my router. My telkom number is ***
