General poor service

I am due for an upgrade. Have been to 3 stores in Cape Town, the Waterfront, City Centre and Sea Point. All 3 do not have the handset I want in store. No one can order the handset in and apparently I just have to wait and see when they receive one. I have tried calling every branch in Cape Town according to Google and can not get through to a single branch over a period of a week. Either straight to automated message or rings till I get an automated message. Have left my details and still no return call. Pathetic service
