Pathetic Online Service

I bought Hisense 415L B/F FRIDGE online, (placed on Fri Nov 06 08:39:03 SAST 2020). I received the dispatch email confirmation same day. I called to follow-up the following week and I was told that it can't be tracked since the tracker number is wrong. I have been calling everyday until yesterday when I was told that my item vanished into thin air and the store it was sent to don't know where it is. So I asked for a refund because I can't deal with the frustration anymore. This morning again I was told that I cannot receive my refund until the item is taken back to the warehouse. Is it my problem that they lost the item, why must I be punished for their unprofessionalism? I want my money so I can go and buy at other reliable companies.
