Poor service and stock issues at Cell C

I have tried to upgrade my current contract and my only request is for a space grey iphone x 64gb. None of your stores seem to have stock and I have been to Sandton, Cresta, ****arney Mall and Campus Square and called Rosebank but no one has stock and apparently the warehouse doesnt know whats going on either. I placed an order for one at Sandton 3 weeks ago but have yet to hear from them. I went to the Cresta branch and at first they were helpful and made out that they have secured one for me but on 4 different occasions phoned back with some painful excuse about a manager, the courier or the other store letting them down. This has been over the course of 2 weeks now. In addition, I have been experiencing dropped calls lately. Please sort yourselves out, including your stock issues and ask the staff at the above branches to be more helpful and informative. If I cant find what I am looking for this week, I will be changing networks.
