Let down by Homechoice incorrect update

I paid up my account and closed it back in 2018. This year upon applying for some huge credit for a purchase,I was informed that they couldn't go through with my application as I have arrears with Homechoice for the past 6 month. When I contacted Homechoice,they denied providing such record. I regret ever having an account with Homechoice.my account number is ***. Really upset!!!!!
