Home choice giving credit to unemployed people and then blacklist them

Homechoice sold me R1000 bedding for 5000.in 2017, while i told them im unemployed and living on my kids grant money. They brought me the bedding but i told them i eont afford it but still they did not listen. I paid 1000 and they sold the dept to norman and basset. Now they say blacklisted me and and tbey say im owing R6000.How am i going to pay for that because im still unemployed. I feel home choice took advantage of me.
