Upgrade from vodacom faulty no customer service

I upgraded more than a month ago and received a faulty phone I've been calling vodacom since I opened the box and the phone was faulty but I still haven't received any help or exchange of the phone. I've spent more than 3 hours on the phone with customer service and that didn't help at all they keep tossing me around from department to department everyone telling me the same thing that they cannot assist or it's not their department or the system doesn't allow them at this point they must just take the faulty phone and cancel my contract with them I'm switching to a service provoder who gives a damn about customer service
