Forced to pay installment for broken furniture

Hi Last year April we bought about 7 items on credit from best home electric in vereeniging. 2 days after delivery I realized that the wardrobe was broken , I asked them to take it and cancel it from my account but they haven't done that. Now almost a year later I'm stuck with a broken wardrobe which they are forcefully deducting money for . I missed a payment for a month and they came to my workplace to collect. My microwave stopped working in November and they only came last week to fetch it. I feel so violated especially after trying to talking to the manager beginning of February and he told me that I must pay the arrears for that one month and then they will pick the wardrobe but they won't refund me .He clearly stated he would rather take that money and pay the other items we took
