Lost TV

I purchased a TV set online, which was supposed to be delivered by Dawn Wing. It was received in Durban on Saturday 19 December, but by Tuesday 22 December I had still not received it. I phoned on Tuesday morning and was told that someone called Dishen would phone me back. Forty minutes later he had not called, so I phoned again. He told me he would phone me back in a few minutes. At about 1.30pm I sent an online request for them to call me. By 3pm I had still not heard from them, so I phoned again and spoke to a manager, Alan. He was aware of the missing delivery, but did not know exactly what it was. When I told him it was a TV, he said that should be easy to trace and promised to phone me back. By 5pm I still had not received a call, and phoned again to be told Alan was not in - he had gone to a meeting. I asked to speak to Dishen but was cut off twice and eventually gave up. I will try again tomorrow. What is so annoying is that this is supposed to be a Christmas present. .
