Luvyle Orderplus International Ltd. Sent wrong item, refused to make it right. Wanchai Hong Kong

I ordered a shirt for my mother, and for my daughter.  The shirts were very slow in coming.  On arrival, the shirt said the correct size, but was child size.  Far too small.  I contacted their customer service by online form and by email to let them know and request a solution.  I was offered four, none of which were acceptable, and each represents deceptive business practice.

The first option offered is to keep the product, which is useless.  I paid for something that I did not receive.  

The second option is to receive a 10% token refund.  This does not fix the problem, and if I want it made whole, must purchase the item again, meaning that I will have paid 190% of the cost of the advertised item: nearly twice the agreed price, with more long delays in receiving the item.

The third option is to receive a 40% store credit, meaning that to use the credit, I must buy from Luvyle again.  If I purchase the same item, this will cost me an additional 60%, meaning that I will have paid 160% of the agreed price for the item, and assumes that Luvyle will get it right the next time.

The last option is to ship the item back to Luvyle at my cost.  The agreed price included free shippping, or shipping was included in the cost.  I did not receive the promised product.  To send it back would cost more than the product.  This is unacceptable.  If Luvyle wants their defective child-size clothing back (it's labled as adult size), they need to pay shipping, and need to either send the correct item, or offer a full refund.  Nothing else is acceptable.  Certainly not attempting to get me to pay for their mistake or to pay twice.

Luvyle tells me that Chinese women are smaller than western women, and therefore it's reasonable to send a child-size shirt, because while it may not fit the customer, it fits the seller.  This is not okay.

When ordering, at no time was I made aware that this was a Chinese company, or to expect such delays.
