Blacklisted for good that I did not recieve

I ordered a bed setting with home choice in 2020 and I never recieved my order. I later received sms from homechoice that I am behind with installment-How to I paid for something that I never recieved? I was avised to contact their ***** department, which I did and I was in contact with a lady called Barbara Motippa who advised that they will investigate and get back to me. This has affected my credit record and I am unable to get credit as I am blacklisted by homechoice. ref number is ***.
