Poor Service and Can't Do what is requested

I am not happy that I received a number from Vodacom that has a very outstanding balance on it. You called me twice within two days, explaining to me that this was someone else's number who either had a business. I got this number for a month now and yet you're unable to resolve your issue. This has caused me now depression and anxiety and more stress. What I want from you now is, within the 24 hours a new handset, with a new contract to resolve the issue. I can be reached on ***. This is my resuest and I don't want to hear anything else, Ican collect the new device with contact at my nearest Vodacom Store. Preferbably the iPhone 6 package. My issue has not been resolved and now I'm receiving demanding for phone calls for payments, from a debt collection company. This has gone now out of hand, I am requesting a new device and a new number immediately, to resolve this issue. Your consultant keeps calling me and asking me the same questions all the time. Please see that I get a new device and a new number as soon as possible.
