Dion Unwired

I bought a tumble dryer on Black Friday a week ago. I expected a delay in delivery and spoke to the sales consultant who advised that my dryer will be delivered on Tuesday, 28 November which I was fine with. Tuesday came and I received my SMS stating that the courier will be in contact as my item has been dispatched. At around 5pm I phoned and Dion said they will follow up on the delivery with the driver and get back to me. In 10 minutes. The following day, without a call received the previous day, I phoned again... The operator said that it is unacceptable and she will follow up with the courier and phone me back in 10... A couple of hours later, same story. And it has been the same story since then, including my last call at 17:55 today, 1 December. I understand black Friday causes havoc and retailers need to cope with it. But it has been a week and I have been very patient, even without receiving promised call backs. I really need my dryer and also need to be able to plan evenings that does not involve me racing home and waiting for my dryer that *might* come. I feel like the issue is with the courier, but that does not mean the onus is not on Dion to ensure I receive my purchased goods.
