Vodacom not honouring Out of Box Failures

I bought a brand new phone from Vodacom and I bought it cash to use as prepaid on Sunday 3 October 2021. I realised at home that the phone was freezing and had a problem with the camera so I factory reset the phone and it did the same. I went in to Vodacom where I bought it and they returned it as a out of box failure. Now my phone has been sent in for repairs even though it is a brand new samsung device. I am still without a phone as at 14 October 2021 and am not able to operate my bussiness without a phone. Vodacom does not realise that this is costing my company a loss of income which they will not cover and meantime they are taking their time. Bottom point is I bought a brand new sealed Samsung device and because it is faulty I would like to have a brand new phone and NOT A REPAIRED DEVICE.
