Unprofessional, and not very good customer care services

Good day Once again Homechoice disappointed me. We have ordered a gas stove online, when the courier company deliver the product, it's been damaged and therefore we told them (the courier comapny) we will not signed for the order and they need to take it back to the HomeChoice warehouse. I've notified Homechoice with regards to the damaged product the same day, and they told me they will reverse back my order once it's been deliverd to they warehouse in Cape Town which will then take up to 2 to 3 weeks. Since today they have not reverse my credits on my account and they now keep on sending me the account bill I need to pay.. How can I pay for the product if I did not signed for this and the product is been taking away the same day with the courier company? I have even once told the call customer person if they do not belive me they must send someone to come and have a look at out house and we even got cameras installed, we could show then the product was send back with the courier company. I demand COD note to see who else signed for this order in order for us to sort it out once and for all. They said the courier company would give us a call and still today we have not received the call from the courier company, which makes me think they signed in behalf for us and took the product themselves which is *****. It's been since May we've been struggling with Homechoice to sort this query.
