This company advertised a lens for sale, i contacted them they confirmed they had stock, so i paid $2500 to them in Jan 2018. In Feb no lens had arrived so rang and cancelled, refund policy takes 25 days. In March still no refund, in April no refund. Contact Business n consumer affairs in May, they suggest i contact my bank. I contacted the bank and a few weeks later they charge back Camera Sky and i have my money back from this dishonest company who hope you go away without your refund.
