Digusted with Telkom service

Beginning of February I bought 50 gigabytes of Telkom anytime data. I still had a good number of midnight surfer gigabytes from the previous 60 gig 60 gig deal they have now done away with. Beginning of April, to my shock, I had run out of data. Yet I downloaded mostly between 1 and 4 in the morning as I knew I would be using up the left over midnight surfer data which only expired at the end of March. My tablet shows I have only used 50 gigs of data since I bought the new 50 gig anytime data. To me, it looks like Telkom disregarded my left over midnight surfer gigs. It also frustrates me that it does not show up on the Telkom app as it has always done. If it did I would not have an issue as things would be in the open and I could see when my data was used up. I opened a case with Telkom who said they would look into it. It took them over a week and me having to phone them for them to get back to me. All I asked of them is that they tell me when my midnight surfer ran out as it does not make sense for me to have used so much data. When the Telkom lady came back to me she could not tell me. I told her that this was unacceptable and that she should phone me on the following day, the 13th of April. I am still waiting for Telkom to get back to me. I have already moved on to another service provider because of this patheticly slow service and I am not convinced that I have had all data owed to me.
