Worst service from Telkom

I had to upgraded my cell phone 4 weeks ago in October I spoke to an agent Amo she told me it will take between 5 -7 days to be delivered and i did advise her that i have moved and i told her what my delivery address should be this was in October and when I called for feedback I was advised that there's no stock and they still waiting and I will be called to confirm once they have stock I did not receive a call ever since and whenever I called they kept telling me no stock of a phone thats been advertised and was offered to me ...last week(now in November) i got a call from a delivery guy who told me that his at my old address and I specifically told agent I moved.i called telkom ever since and every agent I spoke to said they updating this and I should get my order soon. I get an email saying the courier company is sending my phone back to telkom to be redistributed .when I called the call centre they say its been canceled and I must reapply I have gotten the worst customer service possible from Telkom and very disappointed as I have more then one contract with most agents cut the call and was rude and when I ask go speak to a manager they kept transferring calls to another line
