Vodacom bad service and bad iPhone product

So I took the iPhone to Vodacom because the ph was unable to receive calls. Vodacom without my permission adds the caller ID to my bill. How stupid is that. The ph cannot receive calls. What does caller ID have to do with it. So we took it back again. Vodacom gives me a **** replacement ph while they repair mine. I am told that they waiting on parts and they don't know how long it will take. This is a brand new iPhone purchased end March. It's worth r14000. And this is the service Vodacom gives. Never again Vodacom
