Can not get my refund

I bought some items from homechoice(which was falsely advertised) and after i asked about my item and when will i receive it i was told that the item is not as described in the pictures.I therefore requested for the item not to be dispatched and i requested for a full refund which they agreed.Few days later i received an sms stating that my item has been dispatched and i then called and notify homechoice that i don't need the item anymore which they said it must first get to me then i return it to them so that they can give me a refund.Its been three weeks no refund no item and when i call homechoice they are telling me that they don't know either about the whereabouts of my item.Ive been calling for a week now and i get the same response. my call reference number is ********** 66
