You must pay for items that was returned to homechoice

I bought a Brigetta 27pc queen super luxury duvet set and the quality was very poor. I proceeded to return the whole package. The package was delivered on 07/05/2021 and the only collected it on 10/06/2021. 16/07/2021 the phone calls started to claim that all the items was not in the box. They call about 3 to 5 times a day saying I need to pay installments of R231.50 to avoid penalty fees. I don't have any of the items that was sent to me and now I have to pay for it. I think the person who collects the items from you should check if all the items is there before they leave with it because now its their word against yours and they keep calling for you to pay. very very very poor customer service.
