Hello, first purchase from confo and last I bought a duvet cover 2 weeks ago that was not the right size I ask the cashier if it is wrong I can change she said yes keep on the checkout tiket I bring it back closed never open and the after-sales service tells me we don't change and we don't refund the texctil! I can understand if the packaging had been opened there was not! I would never set foot again! Incompetent and unpleasant staff! J is lost 35 but they lose customers !! apparently the staff feel royally crazy! With their old furniture from the 60s, I prefer handmade IKEA !!
