Night Surf Data is a Joke

I have HomeOffice LTE 50gb, I contacted Telkom to inform them my speeds had dropped dramatically over a period of a week, I was told it would take 21 days to simply hear back from them (this after holding on the line for 45min. In the mean time I continued to use my Internet as normal, I set my computer to run updates after 00:00am. The next morning when I checked my data usage through the Telkom app apparently my \Night Time Data\" disappeared and it was using my normal daily data!! I contacted Telkom through facebook and at least there I received a message back. After a couple days Telkom restored my night time data (I could finally see it in the app) but not before I had to reset my password because I couldn't login. However no one has restored my daily data use. Telkom have made an error here - they need to check the usage times and replenish my data during the day, My night time data is finished NOT my data during the day! On another note maybe the call centre agents shouldn't imply it's impossible when it clearly isn't! What is the point of your call centre exactly? To waste time and fix nothing?"
