No Stock for 3 weeks

I placed an order for a Mac Book Air around on the Telkom mobile website around the 14th of February 2018, I then got a call from a lady at a call center to complete my online application. My account was debited around the 20th of February 2018 which the lady advised me off and thereafter i would receive my product 3 days later. I was not told by the person that sold me the item that there is no stock, when i called in a few times i was told that there is no stock and they are awaiting stock, it has been almost a month now and still nothing. I would like my Mac please as i need it for work. Its sad to have to complain on Hellopeter to get some sort of response. I was offered a refund but i just would like to get my product.
