Luvyle Sent incorrect item and, after many email interchange, have not corrected Wanchai Hong Kpng

I ordered a specific item (blouse), in a specific color (gray) with a particular item number (LV_2813252888).  I received the blouse in blue.  When I first notified Luvyle, there was a runaround (several emails) in which they kept asking me the same questions.....like order number, item number, send a picture, etc.  I responded to all of these.  

Then I was notifed that the part number I ordered was for blue.....not for gray.  I responded with the link to their catalog showing the item number as GRAY.  

This was followed by many emails, most of which were repetitive and some beginning as if it were their first notice of the problem....asking me the beginning questions again.

Finally, I thought we have reached agreement.  They asked that I send them $9 allowing me to keep the blue one and receiving the item in GRAY.

Well, stupid me, acting in good faith, sent the money to them.  They have acknowledged receipt of the paymant but have NOT sent the gray.

I have engaged in another round of emails to no avail.  I notified them a week ago that if I did not get the shopping information within the next 3 days, I would report them to the Federal Trade Commission, which I plan to do, but am filing a report with you first.

I have a copy of the entire email interchange.
