They will mess up with your credit record

I bought couches from these people in 2021, entered into a 12 month repayment agreement with them. I paid off my account on the agreed date. 1 year later I find out that my account has been handed over to debt collectors. I call the debt collectors in question to ask about the alleged debt they confirm that my account is paid up but she advised that i call home Italia to find out what the issue is. I call HomeItalia I speak to nelly the manager, she promises to call me back but doesn’t. I call them back and the phone has been switch off since.
