Worst service ever, I want my money back

On Monday the 10/02/2025, I went to the shop to buy a fridge that’s currently on special worth R12 00 ( the Defy 559 L). When I was paying their speed point got faulty but my payment was approved and then their speed point just went blank. However the money went off from my account and since I payed using my apple wallet the transaction also shows there. I left the shop there after giving them some time to sort this out. At first they were denying that my money went through into their account it wasn’t until I came with two consecutive bank statements indicating that I had payed and it shows that money went into their account. Till this day I haven’t received a slip of my purchase, they busy saying they’re sorting things out with head office, and not even communicating effectively. THIS IS BY FAR THE WORST SERVICE IVE EVER RECEIVED, All I want is my money back. Reversed back into my account !!!! I would advise people to be careful with OK furniture, they’re *********** and unprofessional
