GOODS not delivered, 20 days and counting...

I hope and trust you can assist. I fully paid for couches at Olievenhoutbosch branch on the 26/01/2021, 15 days later I haven't received the goods. at the store they keep on telling that they will arrive soon, they are not giving a specific date. Please advise what steps need to be taken for goods to be delivered or get a refund as it is clear FAIR PRICE does not know customer service. The reference number on my receipt is 13441
