unresolvd issue with Homechoice

Homechoice is absolutely disgusting! they had messed up my order last year, the agent i spoke to assured me that when i return the item, they will place another order for the correct items. She did not mention that my voucher will fall off. I returned the item within 7 days, it sat in their warehouse for over 7 days, i was still debited for the incorrect order. I had complained several times, only getting apologies and no compensation...now they are demanding i pay the balance of my account when the issue was not resolved...i told my friends to cancel their accounts with them and they did...terrible customer service, unable to resolve a simple issue...sent emails and was promised i would get a call, its almost a year!!!!
