Do I need to beg to upgrade my contracts!!!!!

I've been trying to upgrade my 2 contracts for the last month now. I walk into your store at Eastrand mall, I encountered an African lady with short hair whose body language was screaming( get out of here! I don't want to deal with you !) When she began to talk , the sarcasm and attitude in her voice complimented her body language. She talked to me as if I was wasting her time and doing myself a favour by being in the store. After being utterly irritated by the fact that you have all these wonderful phones on display but none of which you can actually offer to the customer because they are either discontinued or out of stock. . Next store: Eastgate , I drop off my upgrade supporting documents and the consultant by the name of Buli tells me she will call me in 24 hours with feedback, it's been 2 weeks! I called the call centre to log a complaint and they refer me to the NORTHGATE manager as it is IMPOSSIBLE to contact the Eastgate branch! she tries her \best"to assist but falls short as it has nothing to do with her. next store : Sandton"
