Modlily Wrong sized merchandise and zero response from customer service China Internet

 I order a swim suit in my proper size according to the company's size chart. The cup size was 3 sizes too small and the bottoms were completely the wrong color from the displayed item and not at all the same. Contacted customer service as their email said because this is the only way returns are accepted, zero response from them. Complete and total rip off and I have an item that is never going to fit my cup size and I can't do anything about it. The return label is all in Chinese so there's no way for me to take it into any post office either.
