Poor service at Homechoice

I've been a Homechoice customer for the past year now and I've bought some things from them. sometime last year I bought a 3 piece comforter set and a few months later it began to come loose at the seams. I returned it in November last year and was told that I would be contacted by their customer care department. It has been more than 3 full months and I've heard nothing from them. Instead of assisting customers they'd rather harass our next of kin whose numbers we gave them to use if they can't reach you, their actual customer. My sister receives around 4 to 5 calls from them daily requesting their money.

Their customer care number rings, is answered but the person on the other end seemingly can't hear you. All you get are endless hellos.

How do you request money from an unhappy customer who you've failed in terms of quality for their hard-earned money and service delivery? The matter has not been attended to, yet payment is requested. I am not happy at all.
