refusal to replace damaged goods

I ordered a set of pots, pans and cooking utensils with group on before the christmas break. It arrived early January. When we unpacked the items they were damaged and we followed the instructions to return the box within the given time through local post. <br> <br> In the return I specified that all I wanted was a replacement for the damaged items. Instead I got told they could not replace, only refund. <br> <br> The voucher was valid until June so they obviously have the stock. <br> Now I sit unable to purchase the same deal, but without the goods I bought and with nobody taking any responsibility or replying to messages asking for an explanation or replacements.<br> <br> How can a company sell goods, send them damaged, then refuse to replace them!? <br> <br>
