Cellphone contract not upgraded

It has been more than 3 months now and Telkom Mobile still hasn't upgraded my contract and deliver my new device. This is after several phone calls from me, where I often had to wait 30 to 40 minutes on hold and constantly being transfered from one department to the other with no one being able to help me. What's worse is that their courier has failed on multiple times to deliver to me yet I see trucks from that courier in my building all the time! Also, I never get contacted by them. Their systems can show that the courier returned the package and yet they haven't communicated from their side once! I'm tired of waiting as it seems obvious Telkom isn't interested in my business! Honestly, hellopeter should allow a zero star rating because 1 is being generous when describing Telkom's customer service.
