Disregard for customer and Incompetence

I cannot even begin to express my utter disgust and disappointment in Vodacom. I did an upgrade, low and behold they delivered the wrong phone and a more expensive package. I have been trying to resolve it for a week. Call after call, no one gives a damn. In fact I recieved an SMS stating my query is closed. So my question Vodacom is are you to big to care about me the customer? Is it because you don't have local roots anymore that you think you can treat me like this? I will exercise my CPA right, I will tell everyone I know about your lack of interest and just plain incompetence. P.s. I am a nail technician I have plenty of customers.
