Damaged and wrong size product

I recently ordered a jumpsuit from poetry in size 8 but I got it in a size 6. On the invoice it wrote the right size which is a size 8 but the product was in a size 6 and not only that, it was also damaged it had some holes on it.They inconvenienced me, because I wanted to wear it to a function that I will be attending Wednesday. I am really disappointed. Something must be done

I stay in phalaborwa and there's no poetry around here so I cannot say that I'll return it in store. if I decide to return it I would have to spend more money again because there is no poetry around here and I have no money for a courier.
