Waiting more than 6 months for delivery

I was contacted in June to upgrade my MTN contract and new phone. Before I agreed I informed the operator that the phone can only be delivered on Tuesdays and/or Thursdays seeing as I have end stage kidney failure and is in hospital for treatment the rest of the working week. She told me that this will not be aproblem. But unfortunately the courier company phoned me on a Monday but promised to deliver on Tuesday which never happened. I went to Kimberley's main MTN branch and was assisted by Rencia. Her investigations led to finding out that my new phone was send back to MTN warehouses in Johannesburg. She told me that Johannesburg will contact me. Since then I visited her on a weekly basis with no resolve. Rencia keeps on sending emails to head office and they keeyresponding that they will contact me. When I asked to speak with her manager I got told that she's busy too and cannot help me.Is there anybody else that is prepared to pay for an upgrade for 6 months without the phone or assistance?
