Worse customer service and most overpriced network in SA

I upgraded telephonically about two months ago. I was told that my premium which was previously R299 will be R149 now as it was a sim only package i took with data. Instead my monthly installment is now R339 for the past two months. Everytime i try calling the call centre im told to make use of other options and i never get through to an agent.... You guys are quick to call when u want us to spend money. I reversed my debit order that went off today... Hoping one of ur agents will finally contact me.
