refuse to return delivery charges

I ordered couches, only to receive the incorrect colour and they were damaged. following a long back and forth, they finally agreed to reimburse our funds. Our funds took over 4 days to be paid and on receipt of same, we noted that they failed to reimburse the delivery charges. <br> <br> They claim that delivery is a separate department and that the service was rendered in any event (although in respect of items I never ordered).<br> <br> It have been the most unpleasant experience - and strongly do not recommend them for furniture.
