Order never arrived from Merkado, still no refund

I ordered a hot brush babyliss curler in May. I still have not received my order. I have tried to contact Merkado via phone, their land line does not work, I have sent countless emails and even facebook messaged asking them to refund my order back as they never delivered my order. They ignore my plea for a refund. They are unprofessional and they are a ****. DON'T PURCHASE FROM THEM
