No response - Poor customer service

I went to the Cell C branch at the Bloemfontein Waterfront, as i am due for an cell phone upgrade, I spent 30 minutes in the store being assisted by a gent of which he has taken my details in a little book to phone me back as the branch had no stock available, this was a month ago, till date I was not called back, I went on the Cell C web site as to my surprise I can upgrade on line, I chose 2 phones with the options \call back"with all my particulars and no call received from a cell c consultant"
