Game online don't want to deliver my product

I made an online order on the 24 April 2022 for a washing machine. I was told the machine would arrive the latest the 1st of May 2022. I waiting and only received an sms about my order number on the 26 of April and from there nothing. I made numerals calls to came from the 2nd of May and no one was able to assist me, it's either they calling the store or they just put me on hold till they drop. There was a point where they didn't even answer my calls. I was promised to speak to the manager but nothing. I made calls everyday to the online team 3 times a day until a lady told me the machine was dispatched in Centurion, I called the shop at Centurion n spoke to Abigail and they told me they dispatched the machine on the 24 April to a DSP laser logistics or rather old name by Dawn King to their driver kabelo n they gave me a way bill to track it and its untrackable. I called the laser logistics and they wanted proof from game and game didn't want to provide me with it. They tell me about internal investigations. I send messages to their socials and they only tell me there's an agent working on it and keeps on saying we apolose. They refused to refund me because they say they want to do investigation first. I asked for them to make another order while they investigate n they refused. I'm so fed up with game store

I have piles of clothes waiting for me cos I have 3 toddler at home.im really frustrated and I wish someone tell me what to do since iam taken from pillar to post 😢
