I would like to update my review,
I have to admit that I'm still surprise from the way RC wilie taking care of their customers! I never seen Anything like that.
The manager Adam contact me and promise to have the store manager contacting me asap. The day after I talked with Adam, Sakis the store manager called and explained why the prices are different and what's the quality of each. Sakis was very patience and super nice! After talking with him I understood that I was wrong and the material of each brand is completely different, same as the price. After the detailed explanation I got from Sakis he gave me the option for refund (3 months after) but I decided to stay with my bedroom set.. in fact, I spent another 1000$ after I talked with Sakis ..
Sakis and Adam thank you so much for everything!
