Worst service and forever adding penalties

Worst decision I've ever made taking out a contract with them.

Forever adding penalty charges even after you've made payments while in advance which I end paying anyway each month. They've messed up my credit report so bad saying I have two missed payments which were paid in time btw. This month they added R59 penalty fee again for a bill that was paid in time in May as I changed my debit order to the 20th which was originally on 15th just for a smoother transction

Called customer twice spoke to two agents first one hang up one and didn't call back.

Both angents had no clue about billing of course. Couldn't answer a simple question. Denied me my invoice so I could have a look at them myself and when I requested to speak manager they someone will call me back absolutely appauling service had nothing but problems since I joined
