Slow order wrong size!

I ordered 2 ***L men's shirts from Lightinthebox.com. Paid extra (double) for 2 to 6 days delivery. Yesterday received the 2 shirts after 6 WEEKS! And guess what they are not the same size and much, much smaller than any ***L shirt. Usually the chest of a ***L measures 600mm upwards, but these 2 shirts are 500mm and 540mm. What a waste of money. I have been caught. Be warned.
