Poor service & lack of feedback Client service automated reference number #***0

I upgraded two contracts on the 18th of October. Phones were to be delivered in 3-10 working days. I am still waiting for the phones even though I am being charged the new contract fee. I have made numerous phone calls & keep being promised that my query is being escalated to the Johannesburg supervisors as keep getting through to Durban via the call center. I have been promised many times that I will get a call back from the supervisor within the hour. I am still waiting. Now 2 months down the line I am still waiting. I really do not know what to do anymore. I need to have this matter resolved ASAP it really is enough already. I have sent through an email to customer care with all the details of my calls including names and reference numbers. All i get back is an automated response. PLEASE HELP.
