Bad services from House and home furniture Welkom

It has been more than two years since Rainbow finance has repossessed LG Hi-Fi I bought from House and Home after I lost my job and I only used it for less than six months, yet House and Home furniture says I owe them R14 253. How can I owe furniture that was repossessed? How do I house and home yet rainbow finance paid for that LG Hi Fi since is a loan? Please help.
