Telkom’s disappearing data and poor customer service

I have a 10GB Sim only contract with Telkom. I called in on 10/07/20 to report that my data was showing as “out of bundle” since the 9th when I only started using it on the 6th and know very well that I couldn’t used up the 10GB. Consultant confirmed to only see about 3GB usage and requested I give Telkom 72hours to investigate and come back to me. A case number was smsed but I heard nothing from Telkom after 72hours. I called on 15/07/20 to make a follow up and to my surprise my case was not submitted and the usage now showed 14GB used between the 10th and the 15th which includes 10GB Night surfer. Telkom can’t answer how was the data use when on my side it was reporting as out of bundle. Got an sms on the 18th to say the case was resolved, called in the 19th but the consultant just told me all he can see is that the data was used up, nothing else as a clear resolution of the investigation. Went to the store on the 20th, left my numbers and I was told I’ll be called back after and hour. I haven’t heard anything from Telkom. This is really frustrating!!!
