eBucks store sold me an item they do not have in stock and cannot deliver. No communication re: no stock availability or alternative arrangements

Bought a DJI mavic mini drone on 09-01-2020 which I was expecting to receive within 6 business days just within time before I left for my holiday on Friday 17 January ( I was going to use the drone for some footage I had planned to take). Naturally after one buys a product online they will check the status of the order by way of tracking. On Tuesday afternoon the order status of the order had not changed since money was debited from my account on 09-01. It still said "order received/payment received". Mind you there are still 4 other steps i.e Dispatch, collection by courier, back to courier warehouse before being out for delivery to customer. No status had changed at all. I had phoned the ebucks store 3 times already with the consultants telling me the order will be fullfilled within 6 working days. Until I eventually pushed one of the consultants to be honest with me, whether the shop had the item or not. She confirmed the shop didnt in fact have the item and I wouldnt be able to get the item within the 6 days stipulated. It is highly disappointing that that store could not inform me about this before I had to call and inquire myself. This has seriously hindered my plans for my holiday and as such will not have the item to use. I am thus contemplating cancelling the order and purchasing the item elsewhere where I will receive it instantly. I have now learnt that ebucks store sells items they do not posses!
