Rank Incompetence & ********* Conduct

In early May, my Telkom app recorded that I used 119 GB within a matter of a few days, most of it on the 1st of May. This is impossible. I had a 60GB wi-fi contract with Telkom and my usage history reflects that in most months I don't manage to use even half of that data for the entire month. I live alone and did not use that astronomical amount of data in such a short space of time. When I contacted Telkom to dispute this data usage log I was told that "the system is correct, no forensic investigation was possible, and that I was liable for the bill to follow". I immediately cancelled my contract with Telkom. I have tried to speak to an agent on a number of occasions to determine what my bill will be for May and if there are any cancellation penalties; it is impossible to get through to the relevant department to do this. I have also tried to dispute the bill on the perennially dysfunctional app and this is also proving to be impossible. I am hereby notifying Telkom that I am disputing the bill for May since I did not use 119 GB in that month.
