Sick and tired of waiting for nothing

I'm struggling toe upgrade for 2 months now, due to NO STOCK all the time... my account is never behind or paid late bat still non of the staff at telkom want to do anything extra to help me upgrade. Of the 24 phones on display, they ONLY have 2 in stock, pathetic I'll say. They say they anrn't allowed to order stock from another Telkom branch. What happens if my contract expire? Do I have to settle for a phone that I don't like, to keep my contract going. I get no feedback from customer care an I even app**** online, but still nothing!
