Cell C sales Agent ignoring me?

After numerous emails and requests, Nonkanyiso from Cell C still hasn't responded to my complaint. In short:<br> <br> I app**** for a new contract, and after thy did not have stock in my specific phone size, I compromised by applying for the more expensive one. After two weeks I received my phone, only to see that they sent me the wrong colour. <br> <br> Come on Cell C. What am I supposed to do to get your attention? <br> I've tweeted you, emailed you, phoned you and all you say is that the matter will be escalated. It's been 8 days now. This is by far THE WORST service I have EVER received from anybody. The least you can do for taking my money (more than I bargained for) is to man up and call me.
