Poor, Poor Customer service and interaction

My son's number is due for an upgrade - I went to the Cell C store in Clearwater mall 2 weeks ago to start the process - hoping to get his upgrade sorted for his birthday. He is turning thirteen, so I feel an iPhone 8 is just too much, the "entry level" iPhone offering from Cell C is (was) the iPhone 7, which I was happy to take, and was told to come back when I had time and they'd sort it out for me - 64Gig iPhone 7.

I went back yesterday where I was abruptly informed that they no longer carry that model but I could get an iPhone 8 at nearly double what I'm paying now!!! Obviously I was livid, but was told that I should call (084)145 as they had stock - so I did. I was helped by a lady who, after checking my pedigree, told me that there was stock available but she wasn't fami**** with the deals and asked to transfer me. After being put on hold for 10 minutes, I got through to another lady who started the process again... only to be told that there was only a 256gb item available and that was the best that could be done. After explaim=ning the situation to her, I was told she'll call me back when she has stock of the 64gb - bit she has no idea when that will be!

This lack of interest and sloppy attitude is not acceptable! I spend in excess of R2000 a month with Cell C and this is the first time I'm requesting a handset - surely this is not the customer retention policy for cell C, or is it?
