Cell C just doesn't know what it's doing

I am very disappointed in the service that I am yet again experiencing with Cell C. I have been with the service provider for quite some time now and called to see if I am eligible for an earlier upgrade. I spoke to a consultant on the 11th of October who advised I can call after the 27th and a senior retention agent will be able to assist me as they have the mandate to process upgrades in advance. I called this morning and the consultant informed me I must call after two months. The discrepancy in terms of information is ridiculous you'll speak to one person who will say this than another who will give you a completely different story. I have been with Cell C for many years and always spend extra on my contract so I really do not understand what the issue. I have a contract with Vodacom as well and had to upgrade earlier last year because my phone got ****** they gave me absolutely no hassles. Someone urgently needs to assist me and train your staff properly who give customers wrong advice.
