Tasteless network and support

Honestly, the network, the support, I don't know which is more disgusting. I don't receive calls, I receive SMS's to inform me that I have a missed call. I have logged this issue for over a year (with different devices). Two months after my last call-in, the ticket is still pending. I then get told to dial a number and switch off my phone. "Error performing request. Network failure" I have never failed you. I always pay on time but you have failed me Vodacom, too many times. I run a business and it doesn't reflect well when my clients cannot get hold of me. I will be migrating my services to another network provider.
