Unresolved case

Whenever I increase my limit, Telkom will send an sms notification that my limit has been increased. But then problem is that whenever I load data then it says that I don’t have sufficient airtime whereas the data being loaded is lesser than the limit increased. Looking at my invoice I saw that I was double billed. There is no way of getting help from their call Centre staff. All you hear is giggles in the background. There’s is no any other way of raising our issues with Telkom, except for the hello peter platform.
